Summary of MD.GR0

(MediumDeepFields summary page)

Summary page of information for the MD GR0 (grand reprocessing version 0) including the new reference stacks in the V3 tessellation with the start of new MD10 observations in OC142 (August 2012). This is version 0, the first start of full reprocessing of the MD fields and must be balanced along with other reprocessing, 3PI stacks, nightly science, generation of new reference stacks etc. The new ubercal reference catalog were available starting with MD08 (with PS1.REF.20120325) and MD09 (with a revised REF.20120524), but all others (MD10, 01, 02, 03, 04, 05, 06, 07) were originally processed using the original synthetic catalog. MD01,02,03,05 were not fully reprocessed originally due to various problems, so those fields will have a mix of exposures calibrated with different catalogs. There has continued to be limited reprocessing of MD exposures in order to create new refstacks for the season so there can be exposures with multiple reprocessed versions.

Creation of the new reference stacks need to be, at the very least if possible, made a week prior to the return to the particular MD field given in the current schedule ​http://ps1sc.ifa.hawaii.edu/PS1wiki/index.php/Medium_Deep_Schedule. After the July, August, September time crunch of a new field a month, there should be time to continue reprocessing and creation of new reference stacks in advance.

Notes:

• TBD=To Be Decided/Done by priority, X=not planned, ?=unknown at this time
• 20YYMMDD date entries are part of the data_group name to access via the PSS or Datastore, i.e.,
  • stacks -- MD01.refstack.20110820, MD09.deeptest.20120727
  • night stacks -- a mix of label, data_group formats, see specific section
  • stack photometry -- originally the same date 20120805, but revised runs now have dates for each in the form adding for staticsky .<#>x20YYMMMDD and skycal .cal20YYMMDD.
• (U) updated -- new 2012/2013 versions exist for these refstack now (see MediumDeepFields) but not necessarily used for stack photometry (staticsky/skycal) for loading into PSPS (original MD.GR0 may be deeper and better to use). The refstack used is indicated in the Stack Photometry column. All updated refstacks of course use the ubercal catalog for calibration.
• (R) replaced -- MD09.refstack.20120603 replaced by 20120831 due to variance problems.
• (I) incomplete -- for MD03, 05 stack photometry stalled while data disks being shuffled..
• (mixed)
  • finish reprocessing all exposures to V3 for warp/night stack for MD01+02+03+05 =840+609+1286+1115 = 3850 (2-3 full days of --only-- MD processing) -- finished 12/30/13
  • (mixed) -- both camera/SMF and night stacks can have calibrations based on the synthetic catalogs (initial sample run) and ubercal catalogs (finish V3 run). See specific section for detail.
  • (mixed+full) -- MD05 -- some older and newer processing, so mix of magic and photometry catalog used and then a re-reprocessing of MD05 was done on the exposures originally processed with synthetic catalog. See MD.GR0
• stacks
  • out-of-season/anti-yearly refstacks, yearly refstack: on hold for MD.GR1 (would need to update/reprocess large numbers of exposures to do).
  • iq/psf stack on hold until MD.GR1 (like out-of-season, would required many updates) -- should do for MD04,MD09 and requires development/code time.
  • deep stack for MD04,09 for MD.GR0 only, all others on hold until MD.GR1 (many many updates would be necessary..).
• reminder that ubercal of pixels start with MD08 in the date sequence, finished processing of MD01,02,03,05 exposures into V3 will also be ubercal'd (including reprocessing of any needed to make the complete night stacks)

Questions:

• background restored warps/stacks?
• SMF loaded into PSPS limited to just the ones used in the refstack (or deepstack if available) or all available exposures Camera/SMFs?
• MD01,10 have new refstack for this season, need to decide if using for phot+PSPS (limited set of exposures reprocessed recently to make)? Or use as update test for PSPS?
• MD09.refstack.20120603 suffers from the weight image problem making an arc of lower sensitivity, but warps are still available for doing the deep stacks. 4-6 hrs/skycell to run, ~300 skycells, deepstack pantasks typically has 30 nodes, so ~2-3 days processing time, then redo? -- yes, since MD09 is a new test/comparison set with SAS -- done and date updated under refstack as MD09.refstack.20120831

Feedback is important

We would not want to continue full reprocessing of the MD fields if there has been a gross oversight or problem for a particular science interest. Please let us know of any issues you discover with example details. For example

• tessellation and/or offsets issues in any of the fields
  • corner of skycell.055 seems to be regularly masked (and in neighbors with the overlap)
  • fields with offsets need to include sufficient images in old and new pointings (i.e., MD10), for the magic reference stack at least.
• any issues with masking, mask values
  • been report of possible ones in early MD10 but still need details
• depth/quality of the stacks, reprocessed images in the new format
• any missing skycells, SMFs, other data products -- in particular MD10 which has been the only MD field full reprocessed and magicked for release of SMFs, warps.
  • MD10.refstack.20110722, MD10.refstack.20110821 r-band has two edge skycells (041,051) with poor quality and failed
  • MD10.refstack.20110722 y-band skycell.048 had rejection problem, fixed with MD10.refstack.20110821
• MD10.refstack.20110722 replacement with proper uncompressed MD10.refstack.20110821 for diffims
• with magic turned off now (01/2012), MD04+MD06 have 2+ warp inputs for night stack creation to test how well boundaries come out and has fault/quality issue with 2-3 input cases showing some inputs have incorrect PSF size values measured/passed. rare (~<1%) but should be looked into (ie stack_id=609561)
• adding a quality column to ippMonitor for evaluating missing stack skycells would be useful to have on stack processed skyfile

MD.V3 Tessellation

The new V3 tessellations are defined at PS1_Tessellations with the following general properties:

• 0.25"/pix (from natural ~0.258"/pixel, previously warped to 0.2"/pix up through V2)
• 10 x 10 skycell grid (previously 12 x 12)
• +x is West (flipped from before +x was East), +y is still North
• 320 pixel (80") overlap (from 300 pixels, 60", in V2)
• revised centers (if necessary) -- see relevant MD section for more details and the MDS field table (​http://ps1sc.ifa.hawaii.edu/PS1wiki/index.php/Medium_Deep_Survey#Actual_Field_Centeres_-_2011-02-21) but in summary
  • MD10.GR0: from (351.979 -0.433) to (352.312, -0.433) however an additional offset looks like it should have been applied to cover more of the earlier observation dithers.
  • MD07.GR0: from (213.146, +53.417) to (213.454, +53.243) to best cover as much of the earlier observation dithers as possible.
  • MD08.GR0: very slight offset in RA to the W to just align with the MDS field pointing.
  • MD09.GR0: from (333.688, +0.283) closer to the current pointing of (334.188, +0.283) however an addition offset was added to move the center about half a skycell to the E to (333.980, +0.283) in order to cover as much of the earlier observation dithers as possible.
• All fields should be looked at to see if there are any problems with the new tessellation and dither pattern.
• MD07, MD09 will have a preliminary night stack made for testing the revised center as well as MD06 for NGC4258.

Reference versus Deep Stack

A requirements description for the needs in the different types of stacks would be useful to summarize.

Reference stacks -- primarily for difference imaging for transient detection and necessary for magic destreaking.

• Magic destreaking: a fairly clean reference stack (uses the convolved stack) with as much spatial area coverage as possible to enable release of non-stack data products. Particularly important is inclusion of older data on different pointings and of course a fairly balanced dither set.
• Transient detection: a balance slanted towards best PSF but with some depth (1-1.5 magnitudes over night stacks) and also a fairly balanced dither set. better with more recent data to limit AGN/variable star variations.

Deep stacks -- for deep static sky science.

• As deep as possible.. maximum FWHM allowance? minimum exposure time? specific request for at least ~10ks has been requested, with best FWHM possible and also a fairly balanced dither set..

See summary for each MD field reference stack for details on specifics for that field. Due to processing+time constraints/early mistakes, an attempt has been made to merge the similar criteria under the refstack label.

Since magic destreaking uses the convolved stack, looking into a quickstack version of the unconvolved stacks for the transients reference and deep stack that will be faster to make with more inputs.

For cases when a stack does not have a good sample of exposures with a reasonably small PSF FWHM, it should be possible to generate a reference stack with the fewer 'best' exposures for just SSdiffs and transient detection. MD02-g may be such a case.

For fields with shifted centers from offset earlier exposures, inclusion of enough exposures to provide a reference stack for magic is necessary in order for data from those associated chips/skycells to be distributed (being older data, may not have the optimum quality). Mixing older and newer data may also be a detriment.

Related to deep stacks, there needs to be enough inputs to obtain minimum depth that is as pixel contiguous as possible (see MD04 deep stack tests).

How much of a varying IQ can go into a stack before ppSub has difficulty modeling the variations within a skycell?

Deep stacks on hold until finish investigating overly large PSF in the convolved stacks dependent on the number of input warps.

Without need for magic for releasing older data, should focus on more recent data going into the refstacks

post-Magic January 2012

Reprocessed Data Products

Each MD field has a variety of issues and details are summarized in each MD section. Label/data_group names have also evolved and the appropriate MD section should be referred to.

Chip+Warp

Currently processed but not distributed due to disk space load. Can be obtained via the Postage Stamp Server.

• can be a mix of synthetic/ubercal catalog calibrations except MD08, 09

Camera/SMFs

Fully processed and distributed.

• can be a mix of synthetic/ubercal catalog calibrations except MD08, 09
• a possible guideline to follow, including nightly science data processing, if MD exposures with a cam_id >= 412069 is used, those will be with the ipp-20120404,r33642 tag that includes the faint-end bias fix and the ubercal catalog 20120524v0 version also used for LAP.

Stacks

Night Stacks: All nights reprocessed and stacked into a night stack using the current night stack configuration used for nightly science night stacks when processed, including reference catalog

• should attempt to make stack with 2 or more input warps now
• some nights have >8 exposures, often in marginal conditions. Since marginal conditions can vary greatly, some selection should probably be made for inclusion in the night stack.
• the sample of stacks can be a mix of synthetic/ubercal catalog calibrations but NOT for the warps going into the stack itself.

Reference Stacks (refstack): To be made prior to the start of the MD field observations for the season to support the difference image products (magic and science). The focus of MD.GR0 was on the 2011/2012 season fields starting with MD10, then 01, 02 ... through MD09. The 2012/2013 season refstacks will to replace the 2011/2012 set and have their own page linked from MediumDeepFields.

• out-of-season/anti-yearly refstacks, yearly refstack: on hold for MD.GR1 (would need to update/reprocess large numbers of exposures to do)

Deep Stacks (deeptest): Not a full production product yet. Test version exists for MD02.iqtest.20120927, MD10.psfrefstack.20110814.

IQ/PSF Stack: on hold until MD.GR1 (like out-of-season, would required many updates). A sample for MD09 done but requires development/code time.

Difference Images

Originally a possible reprocessing product, but was decided not useful at this time (for future reprocessing, need to outline interests for these if any). Will need to finish the convolution choice (input stack or reference stack) before started.

Stack Photometry (Static Sky + Skycal)

Stack photometry (staticsky) and recalibration (skycal) is run on refstacks, deepstacks and night stacks. In trying to run as a uniform group, will keep a summary here, but details like specific faults, poor quality etc will be in the respective MD section when time. For example some skycells can have a clear offset fix to the zeropoint, not actually set to 25.0 in stack pixels, for some the majority of the field is off from zeropoint of 25. There appears to be upwards of 3-5% error likely in the photometry across the FPA (see MD.GR0) even in the recalibration of the stack photometry (skycal stage). A much worse example is seen in MD01.refstack.20120803.

• recalibration of the stack photometry catalogs has no method for distribution -- email for access

Current run planned for loading into PSPS (January 2013): stack photometry (staticsky) re-run from Summer 2012 set to incorporate improvements/fixes in the Kron code. Photometry zeropoint recalibration (skycal) re-run to incorporate various bug fixes and improved tuning (psastro running on stack catalogs). Several previous re-runs for skycal and settled on .cal20130128 version for now.

MD10.GR0

Status:

• reference stack (revised) processed and distributed. All exposures since April 2009 reprocessed and distributed except for SSdiffs. SSdiffs being held back until ppSub auto convolution choice is tested on.
• 8/2012: to be replaced with MD10.refstack.20120705, then replaced with MD10.refstack.20120804. See new refstack wiki for old/new refstack comparison maps.

Started for OC142 (July 15, 2011). Start with current statuswith a new reference stack and full sample of reprocessed exposures as an initial reprocessing version.

• z,y-band data processed prior to full Dark model improvements (higher background makes effect insignificant). gri-band processed after Dark model improvements.
• same photometry reference catalog as MD have previously been using.
• stack-stack diffims still using forced convolution of reference stack to input images

MD10.V3 center shifted to the current observation pointing even though there are earlier data that has offset dithered observations that populate the 0X8-0X9 skycells. Not as bad as MD07, but the revised reference stack may not provide for the outer skycells very well. Afterwards it was discovered the full extent of the previous observations wasn't quite accounted for, shown by these exposure plots with the MD10.V3 overlay and compared to a recent night stack set of exposures. This may need to be shifted in the next iteration.

Exposures available with preliminary FWHM cut for initial reprocessed sample to create the refstack:

Filter	N total	N (FWHM<upper limit GPC1 pixels)
y	136	all
z	246	136 (<5.0 pixels), then finished reprocessing all
i	256	149 (<7.0 pixels), then finished reprocessing all
r	253	159 (<7.0 pixels), then finished reprocessing all
g	242	118 (<7.0 pixels), then finished reprocessing all

• also initially attempted to include some rough cuts by zeropoint and background (in 20110722) but after reprocessing all exposures wouldn't be included in the stacktool selection based solely on basically FWHM major. (improvements to selection and rejection for a future test)

MD10.V3 reference stack

• label: MD01.refstack.20110820
• data_group: MD01.refstack.20110820

Initial goal was to maximize depth while minimizing the PSF FWHM with enough inputs (4 or more) to produce a stack for all skycells covered, in particular

Compared to the cumulative metrics at ​http://ipp0022.ifa.hawaii.edu/ps1sc/metrics/range_2010-05-13_current/

Histograms of the FWHM major and minor from camera stage for reprocessed g-band exposures (red) and refstack.20110722 (top blue), psfrefstack.20110814 (middle blue) and refstack.20100721 V2 (bottom blue). The unmatched blue/red overlap for refstack.20110722 FWHM major<6.5 pixels for exposures in the refstack is from using also low zeropoint and bright background cuts. Psfrefstack used <5.1 pixels.

The same refstacks with the selected exposures over time

Sample skycell coverage map by good_frac with N input warps, N rejected warps, dtime_script for making stack, and if quality error that rejects entire skycell. The ~130 input warps provided enough of a sample for the outer edge skycells from earlier exposures.

In tracking down an odd skycell (048, y-band), an odd rejection case was highlighted and prompted a modification to the rejection criteria based on the RMS of the stamps (see r32170). This may help reduce large number of rejections in future refstacks but likely needs some tuning (currently still rejecting too many?). Using the PSF FWHM cuts in the DEEP_STACK reduction also helps reject strange input warps as well.

Initially the stack processing was run without a reduction type and thus with just defaults that compresses the images (version 20110722gri, 20110715y, 20110718z) along with a test sample to produce the best PSF focused set (MD10.psfrefstack.20110814) and a test best deep stack (just skycell.055, i-band, not distributed). This is not optimal and a re-run was done with the DEEP_STACK reduction type (version 20110821) and should be the one used. The different reduction types include:

NULL (none/default values used from recipes/ppStack.config unless defined in gpc1/ppStack.config):

• PSF.INPUT.MAX F32 NAN
• PSF.INPUT.CLIP.NSIGMA F32 NAN
• OUTPUT.NOCOMP BOOL FALSE
• OUTPUT.LOGFLUX BOOL FALSE
• OUTPUT.REPLICATE BOOL TRUE

DEEP_STACK:

• OUTPUT.NOCOMP BOOL TRUE
• OUTPUT.LOGFLUX BOOL FALSE
• PSF.INPUT.MAX F32 7.5 (should add to PS1_REFERENCE as the reduction to use for refstacks)
• PSF.INPUT.CLIP.NSIGMA F32 5.0 (should add to PS1_REFERENCE as the reduction to use for refstacks)

• OUTPUT.NOCOMP BOOL TRUE
• OUTPUT.LOGFLUX BOOL FALSE

• OUTPUT.LOGFLUX BOOL FALSE

THREEPI_STACK: (for comparison)

• PSF.INPUT.MAX F32 12.0
• OUTPUT.NOCOMP BOOL FALSE
• OUTPUT.LOGFLUX BOOL TRUE

QUICKSTACK_DEEP METADATA (testing unconvolved stacks version only, similar to QUICKSTACK)

Using the MD10.refstack.20110722 and related set, histograms and mag-magerr plots for the reference stack, deeprefstack test, psfrefstack, typical night stack and V2 refstack are compared. The re-run MD10.refstack.20110821 will go a little deeper than the psfrefstack version.

A representative skycell mapping of the new tessellation and good_fraction coverage. Night stacks will have similar, if not more, trouble with covering the corner edge skycells: 012, 017, 021, 028, 071, 078, 082, 087.

Other plots that may be good to see

• Mask fractions vs V2
• mapping of all exposures WRT new tessellation to check maximum coverage given some fields offset and others have had extra dither patterns (i.e., like MD10)

Troubled skycells for MD10.refstack.20110821:

Started for OC144 (September 12, 2011) with a new reference stack and a small sample of reprocessed exposures to release night stacks as well. Due to a need of rebalancing the reprocessing load, only a minimal amount of processing required to make the reference stack was done.

MD02 does have some offset dither exposures illustrated in the sample g-band V3 plot, but many are single exposure coverage and won't typically be enough for a reference stack skycell. While warps will extend to some of the outer skycells, the night stack distribution will define what is likely for the skycells released due to magic. 012-017, 21-28, 31-38, 41-48, 51-58, 61-68, 71-78, 82-87

Exposures available with preliminary FWHM cut for initial reprocessed sample to create the refstack:

Filter	N total	N (FWHM<upper limit GPC1 pixels)'"
y	224	97 (<5.0 pixels)
z	526	150 (<4.2 pixels)
i	488	163 (<4.8 pixels)
r	377	160 (<4.9 pixels)
g	388	147 (5.5 pixels)

• the number of exposures being reprocessed have been increased from that in MD01,02 in order to at least attempt to match the input warp numbers in the previous MD03.refstack (~100).

• overshot the number of input warps compared to V2. The average PSF FWHM_major seems much better than expected from the histograms (above) of input exposures.

Troubled skycells: none on initial inspection. Far outer edges with few dithers may/may not have successful skycells. Sample skycell coverage maps for V2 and V3 with good_frac with N input warps, N rejected warps, dtime_script for making stack, and flag of any quality error that rejects an entire skycell (ERR). The ~110-125 input warps provided a sample for some of the far outer skycells from earlier dithers to be covered still.

Distributed under ps1-md-refstack

Data volume on disk: ~330GB

Processing time summary: 12-18000 sec for 100-125 input warps. ~6 days to reprocess a ~50% of exposures through warp, create reference stack, and distribute (along with LAP and normal nightly science).

• was an minor error in the cutoff for i,r: a fewer number in i-band and few more in r-band compared to others. Should be okay for basic refstack, and planned deeper stack should offset any deepstack concerns.

Troubled skycells: none on initial inspection. Far outer edges with few dithers may/may not have successful skycells. Sample skycell coverage maps for V2 and V3 with good_frac with N input warps, N rejected warps, dtime_script for making stack, and flag of any quality error that rejects an entire skycell (ERR). The ~110 input warps provided a sample for some of the far outer skycells from earlier dithers to be covered still.

MD06.GR0

Status: Refstacks and full set night stacks finished and distributed. Camera SMFs also distributed.

• 11/18: all filters all exposures running chip->warp
• 11/23: reftest samples running
• 11/28: disk/data corruption. on hold.
• 12/22: repairs mostly finished and restarted refstacks.
• 12/31: more corrputions found during distribution, fixed.
• 01/01/2012: Refstacks and sample night stacks finished and distributed.
• 01/11/12: reprocessing of all night stacks possible in V3 started
• 01/17/12: majority of all night stacks on datastore. A few faulted with various issues mainly from stacks with 2-3 inputs on far edge skycells.
• 12/21/12: new refstack MD06.refstack.20121221 will replace this one for diffims in the 2012/2013 season

New observations planned and started in OC148 (January 8, 2012).

All past g-band exposures in the V3 tessellation (other filters nearly identical).

Need to investigate tessellation center and dither for science with NGC4258

Exposures available and with preliminary FWHM cut of ones <2". All exposures were reprocessed for this field to be available in creating the refstacks and deepstacks.

Troubled skycells?

• skycell.087 i-band had quality failure, rerun excluding some earlier warps and okay. Needs more investigation into why it had a problem, others with quality issue may be similar.

Status: Refstacks and sample night stacks finished and distributed.

• 10/12: all filters all exposures running chip->warp
• 11/6: all warps finished, y-band refstack started.
• 11/07: y-band refstack finished, z-band started, reftest samples run
• 11/08: zirg refstack running, night stack samples spanning the period since 4/2009 running.
• 11/12: full refstack set, night stack samples finished and distributed
• 6/18/12: staticsky run attempted, see notes below
• 01/09/13 MD07.refstack.20130102 to replace 2011 season refstack

Coming soon. New observations planned for OC149 (February 7, 2012).

All MD07 g-band images over the V3 tessellation with an offset from the current pointing center (shown by the MD07 z-band night stack exposures from 9/28/11) in order to include as much of the earlier exposures as possible.

Exposures available and with preliminary FWHM cut of ones <2". All exposures were reprocessed for this field to be available in creating the refstacks and deepstacks (more important for this field given the two pointings since 4/2009).

• seems to be some strange rejection behavior in at least the i-band.

How well does the "best" selected inputs cover the two pointings?

• note (V0) y-band refstack was at newer pointing, how many y-bands in old pointing?

Troubled skycells?

• 030-z quality fail
• first pointing (older data) skycell coverage needs further looking into. generally includes 093,094,095,096, 086,087,088, 078,079, 068,069, 059, 049, 039
• 077 large rej %, looks like for older data coverage

MD07.GR0 reprocessed sample

Reprocessing of chip-->warp done mostly with condor. Hiccup with loss of tmp files stalled things in the middle of warp, but pantasks picked up the processing fine using the label.

• label: condor_MD07.V3_01
• data_group: condor_MD07.V3_01_dg
• dist_group: NULL, changed camera to MD07.GR

Reprocessed night stack sample under the following label and data_group.

• label: MD07.GR0
• dist_group: MD07.GR
• data_group of initial sample of night stacks processed with both ipp-20110622 and ipp-20111110 tag (see date) and using the default 4 or more input warps necessary to make stack

Staticsky: only run on refstack skycells with all 5-filters available. This run is on stacks prior to ubercal catalogs so the zeropoint is fundamentally based on the synthcat values. This run provides a sample for testing the stack calibration stage. However, many faults (25/70 runs, i.e. skycells) occurred in the processing and need to still be investigated.

label: MD07.refstack.20111106 data_group: MD07.refstack.20111106.5x20120618 dist_group: MD.staticsky (TBD)

Distributed on datastore under

• ps1-md-GR: sample of night stack images only (setting up for full set). SSdiff sample still to be run.
• ps1-md-GR-cat: camera SMFs loading (have the data_group condor_MD07.V3_01_dg)

MD08.GR0

Status: In progress

• 11/25: all filters all exposures running chip->warp
• 11/28: disk/data corruption extensive. will need to be restarted from scratch once diskspace available.
• 4/18/12: restarted from scratch after raid crash in November/December with the new ipp-20120404 tag to include new ubercal refcat (PS1.REF.20120325) and detrend improvements (dark modes, noise map but not the boost factors).
• 4/20: gri reprocessing finished and refstacks started. zy prepped but delayed until 4/22 for other tests.
• 4/21: gri reprocessed camera SMFs and night stacks distributed, reference and test stacks also distributed
• 4/22: z reprocessing started
• 4/24: zy reprocessing finished, zy refstack started
• 4/25: all night stack reprocessing finished, all refstacks finished and distributed, staticsky run and distributed.

Coming soon. New observations planned for OC152 (May 5).

All past g-band exposures in the V3 tessellation (other filters nearly identical).

Exposures available and with preliminary FWHM cut of ones <2". All exposures were reprocessed for this field to be available in creating the refstacks and deepstacks.

MD08.V3 reference stack

Reference stack using data from 2010+2011, a balance of N input warps versus best seeing, excluding exposures with large background, low zeropoints, and large elongation.

• label: MD08.refstack.20120422
• data_group: MD08.refstack.20120422

Test stack (reftest) sample also made again for skycell.055 with different number of input warps.

• label: MD08.reftest.201204xx (xx=17 for g, 18 for r, 19 for i, 20 for z, 21 for y)
• data_group:
  • MD08.reftest.201204xx.c#f<FWHM cut> where #=comparison run, <FWHM cut>=cut <fwhm_major from camProcessedExp
  • MD08.reftest.201204xx.all.<FWHM cut> where all means 2009+2010+2011 data possible, <FWHM cut>=cut <fwhm_major from camProcessedExp
  • MD08.reftest.201204xx.2011.<FWHM cut> where 2011 means 2011 data only, <FWHM cut>=cut <fwhm_major from camProcessedExp

• i-band is an odd situation, 2010 had smaller FWHM with many exposures <1" versus 2011 with only a few <1" so 2010+2011 FWHM~1.09" with just ~15 more inputs.

Test psphot run on refstack

Troubled skycells

• Previously had a few missing skycells in center and around edges (g-band example left). New has only a couple quality failures in i-band for skycell.087,012 (right) that at some point should be manually recovered.

Staticsky: only run on refstack skycells with all 5-filters available and distributed under ps1-md-staticsky. Convolved matching to target PSF much improved, generally the 4-6 pixels now similar to upper input PSF cutoff except for oddities that drive edge skycells >10,20,70 pixels. Work continues to better constrain selection of the target PSF.

• 6/07: refstacks finished and distributed, staticsky on refstack finished, 90% of camera SMF and night stacks that are possible distributed (see listing below for dates of incomplete processing).
• 7/29 MD09.GR0 XY67,71 chip problem (~48 exposures) cannot be fixed so set to poor quality, remaining camera SMF and night stacks processed and distributed.
• 8/31 replaced with MD09.refstack.20120831 to fix the weigh pixel problem causing arc region of lower sensitivity

Coming soon for new observations planned for OC153 (June 3). Observations attempted earlier but weather has prevented.

All MD09 g-band images over the V3 tessellation with an offset from the current pointing center (shown by the MD09 z-band night stack exposures from 9/28/11) in order to include as much of the earlier exposures as possible.

Exposures available and with preliminary FWHM cut of ones <2". All exposures were reprocessed for this field to be available in creating the refstacks and deepstacks.

MD09.V3 reference stack

Reference stack using data from 2010+2011, a balance of N input warps versus best seeing, excluding exposures with large background, low zeropoints, and large elongation.

• label: MD09.refstack.20120603
• data_group: MD09.refstack.20120603

Test stack (reftest) sample also made again for skycell.055 with different number of input warps.

• label: MD09.reftest.20120602
• data_group:
  • MD09.reftest.20120602.c#f<FWHM cut> where #=comparison run, <FWHM cut>=cut <fwhm_major from camProcessedExp
  • MD09.reftest.20120602.all.<FWHM cut> where all means 2009+2010+2011 data possible, <FWHM cut>=cut <fwhm_major from camProcessedExp
  • MD09.reftest.20120602.2011.<FWHM cut> where 2011 means 2011 data only, <FWHM cut>=cut <fwhm_major from camProcessedExp

	Histograms of the FWHM major and minor from camera stage for reprocessed all exposures (red) and refstack.20120603 (top blue) and refstack.20100721 (bottom blue).

Summary comparison table with the approximate FWHM (major) as the PSF FWHM from a center field skycell (V3=055, V2=078) after running psphot on the stacks. Because the reftests were all run on the same date, the stack_id is important to note to separate by filter as well.

Test psphot run on refstack

Troubled skycells

• Previously had a few missing/faulted skycells around edges (i-band example left). New refstacks do not have any quality failures so far and note the current nominal position of the populated skycells is shifted leftward (middle) to accomodate the reprocessing of the night stacks with the early pointing (right).

MD09 revised refstack.20120831

The refstack should be nearly identical (using the same warp processing) except for the removal of an arc of lower sensitivity/depth from the stacking process

• label: MD09.refstack.20120831

• features/artifacts
  • seeing "schools" of ghosts in the stacks like MD08?

• odd images to beware of --

• sample still unprocessed due to XY71,67 faults. tracing/debugging of new ops tag required to fix.
  • seems to be problem with psphot from ipp-20120531 tag, tests work with ipp-20120626 tag. these will be given a quality fault of 42 so that the exposures and night stacks can finish.

Stack Photometry (staticsky+skycal):

Originally, only run on refstack skycells with all 5-filters available and distributed under ps1-md-staticsky. Convolved matching to target PSF much improved, generally the 4-6 pixels now similar to upper input PSF cutoff except for oddities that drive edge skycells >10 pixels (extended source measurements should be on the RAW/unconv image in this tag however). Work continues to better constrain selection of the target PSF.

• Nigel finds RA_PSF,DEC_PSF still NULL for these -- should be fixed now in future versions (8/2012)

Re-run version Jan. 2013: using replacement refstack.20120831

• staticsky (stack photometry):
  • label: MD09.refstack.20120831.N20130115
  • data_group: MD09.refstack.20120831.<N>x20130115 -- <N> = 1,2,3,4,5 and number of filters available for the set, so 5 different data_group per MD

Calibrated stack photometry appears suspect to at least 0.03-0.05 (have seen much worse in other fields):

skycell overlap match mag comparison
refcat match mag comparison example: appears 0.03-0.05 mag error in pixels (staticsky)
refcat match mag comparison example: appears 0.03-0.05 mag error still in photometry recalibration (skycal)

Difference Images: sample still to be run? Not going to be produced for MD.GR0
