IPP Progress Report for the week 2012.05.21 - 2012.05.25

(Up to IPP Progress Reports)

Eugene Magnier

Serge Chastel

• Off on Mon and Tue
• Still working on files monitoring.

Heather Flewelling

Almost entirely a week of PSPS:

• liason - yanked raw files for Craig
• PSPS
  • investigation why stackDetectionFull had funky numbers (Nigel noticed this)
  • found at least one of the bugs: if stack mag = null then set psps instFlux = ipp instFluxSig *2. There was a missing factor of exposure time, causing the limiting mags to all be around 16th.
  • lots of querying PSI to investigate SA5/SA6.
  • made SA6 with bug fix
  • more sorting out of PSPS accounts I need

Roy Henderson

• lots of long emails for PSPS-help explaining the use of infoFlag
• added section to PSPS FAQ regarding above

Mark Huber

• Czar Friday. Caught up on DRAVG minutes. Reran and collected mask stats on another footprint test for Chris, compared MD08. Worked a little with Conrad on matching PS1 and 2MASS catalogs in PSPS for a color-color plot.
• ppSub tests --
  • finished manually setting up, running, making sample plots for another ad hoc sample of of IPP diffims with specific events from Ken Smith. Info sent to Ken, details can be found at ​http://svn.pan-starrs.ifa.hawaii.edu/trac/ipp/wiki/ppSub_testing_201201#ExtraIPPComparisonSet20120516
  • collected absphot catalogs from Sept. 2011 used for photpipe and dumped ubercal refcat used for IPP diffims of for comparison. Quick MD04 comparison seems to indicate there is an offset. Info sent to Ken, details can be found at ​http://svn.pan-starrs.ifa.hawaii.edu/trac/ipp/wiki/ppSub_testing_201201#ExtraIPPPhotpipeCalibrationCatalogs20120524
• STS.refstack -- STS warp-stack diffim sample had a problem in publishing, chose new sample of nights for diffims and out to publish datastore IPP-MOPS-TEST2 now for MOPS to look at. Info sent to Larry, details slowly being added to the STS.refstack page, being the main purpose of the refstack ​http://svn.pan-starrs.ifa.hawaii.edu/trac/ipp/wiki/STS.refstack.20120510
• ppStack -- trickling progress made in wrapping up past tests and cleaning up to then re-start the target PSF tests.

Bill Sweeney

• Continued working on psphot. Attempted to test the new kron code psphotStack on the SAStest.v4 stacks and found all sorts of problems. At about the same time PSPS users reported insane magnitudes in the corresponding data there. Tracked this down to be a difference between the background levels in the raw (unconvolved) stacks and the convolved stacks. Fixed that by modeling the background separately.
• Found that the kron radii measured with the convolved stacks were unreasonably large. Reevaluated the results of the investigation reported last week and changed the recipe values to remove the window and weight function.
• Investigated why psphotStack was still getting duplicate detections during pass 2 even with the footprint fix reported last week. The problem was with the management of the data inside psphotStack. Fixed.
• Wrote a tool to extract the extended source parameters from our cmf files and to read them into mana. Used this to evaluate the extended source measurements on one of the SAS stacks. Reported to DRAVG. ​http://ps1sc.ifa.hawaii.edu/PS1wiki/index.php/DRAVG_telecon#psphotStack_photometry
• fixed data store "feature" (now considered a bug) where if the last_fileset argument to a data store product list function is not found the whole list is returned. This is not part of the spec but is what conductor does. Unfortunately it caused chaos with the postage stamp server.

Chris Waters

• Constructed new mask files that remove static issues due to crosstalk bleeds/etc. If these need to be rolled back for some reason, I have a script located in /data/ippc18.0/home/watersc1/static_masks.20120521/register.abort that resets the det_type to MASKTEST, moving them out of the way of processing.
• Cleaned up LAP stacks from the distribution server.
• Re-enabled shuffle to move data to the ATRC.
