[[PageOutline]]

Summary page of information for the MD GR0 (grand reprocessing version 0) including the new reference stack in the V3 tessellation with the start of new observations of MD10 in OC142. This is version 0 as the test start of full reprocessing of the MD fields to be balanced along with other reprocessing, 3PI stacks and nightly science, generation of new reference stacks and as of yet chip/camera processing does not include a revised reference calibration catalog (currently applies to MD10, 01, 02, 03, 04, 05, 06, 07). 

Creation of the new reference stacks need to be, at the very least, made 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.
 * ''8/15/11'' minimum mode re-processing for reference stacks after MD10 for evaluation and get next MD field ready (MD01)
 * ''9/30/11'' more success weaving in reprocessing with LAP, started reprocessing for refstacks MD03,04 (with more reprocessed exposures)
 * ''10/09/11'' MD03 refstack and sample stacks available, testing MD04 ~200 very deep stack, MD05 running
 * ''10/17/11'' MD07 chip-->warp processing started with condor, using any extra cpu cycles. 
 * ''11/06/11'' MD07 refstacks being made with order ~120 inputs. MD04 deepstack testing continued, gri sample released, zy on hold until fixes made.
 * ''11/18/11'' MD06 chip->warp processing running with condor, refstack preparation (using new ipp-20111110 ops tag now)
 * ''11/25/11'' MD06 reftests made and y-band refstack started, MD08 chip->warp processing via condor, refstack preparation
 * ''12/02/11'' MD06/08 on hold, data uncertain with ipp064 down.
 * ''12/20/11'' MD06 processing recoverable, refstacks proceeding.  MD08 a mess and will need to be re-run.
 * ''12/31/11'' MD06 finally finished, distributed.
 * ''1/09/12'' MD08, 09 on hold while finishing up full reprocessing and release of V3 products now (i.e., nightly stacks, SMFs, SSdiffs).
 * ''1/11/12'' MD06,04 full camera SMFs on datastore, MD07 later today. MD04 set has some duplicates with both unmagicked SMFs (data_group=MD04.GR0, sub-sample of ~150/filter best seeing) and magicked SMFs (data_group=condor_MD04.V3_01_dg, full sample of ~400/filter loaded into PSPS Nov. 2011)
 * ''1/11/12'' full V3 nightly stack reprocessing with MD06 started. -- important note: these are now being run allowing 2 or more inputs to make a stack (down from 4 during the magic era) so outer skycells may have strange behavior that we need feedback on.
 * ''1/17/12'' majority of MD06 full reprocessing of nightly stacks on datastore. MD04 full V3 nightly stack reprocessing started.
 * ''1/23/12'' MD04.V3 full reprocessing of nightly stacks finished and pushed out to datastore.
 * ''4/17/12'' MD08.V3 restarted from scratch after raid crash in November/December and will include new ubercal refcat (PS1.REF.20120325) and detrend improvements (dark modes, noise map, but not boost factors).

* '''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, MD04+MD06 have 2+ warp inputs for nightly 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 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 [wiki: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
   * [wiki:MD.GR0#MD10.GR0 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.
   * [wiki:MD.GR0#MD07.GR0 MD07.GR0]: from (213.146, +53.417) to (213.454, +53.243) to best cover as much of the earlier observation dithers as possible. 
   * [wiki:MD.GR0#MD08.GR0 MD08.GR0]: very slight offset in RA to the W to just align with the MDS field pointing.
   * [wiki:MD.GR0#MD09.GR0 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. 
 *  [wiki:MD.GR0#MD07.GR0 MD07], [wiki:MD.GR0#MD09.GR0 MD09] will have a preliminary nightly stack made for testing the revised center as well as [wiki:MD.GR0#MD06.GR0 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 nightly 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

= 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.

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 nightly stack set of exposures. This may need to be shifted in the next iteration.

== 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

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:

 * 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 nightly stack sample under the following label and data_group.
 * label: MD07.GR0
 * dist_group: MD07.GR 
 * data_group of initial sample of nightly 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

Distributed on datastore under 
 * ps1-md-GR: sample of nightly 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)

''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 to include new ubercal refcat (PS1.REF.20120325) and detrend improvements (dark modes, noise map but not the boost factors).

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

All past g-band exposures in the  V3 tessellation (other filters nearly identical).  [[Image(MD08_g_smf.png,200px)]] 


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).
