IPP Progress Report for the week 2012.05.07 - 2012.05.11

(Up to IPP Progress Reports)

Eugene Magnier

• I worked on the photometric ladder paper; I have a draft, but it needs more work. I also need to refine the subsample selection a bit
• I updated dvomerge
  • added the ability to merge into a parallelized dvo database
  • added code to save the size and moddate of each input table when merged into the master database. this allows us to re-merge after a failure and only have the previously un-merged tables merge.

Serge Chastel

• Fixed ipp001 replication
• Czar on Friday
• Disk monitoring See ​http://ippmonitor.ipp.ifa.hawaii.edu/diskMonitor

Heather Flewelling

• PSPS
  • MD04
    • ran relphot on MD04.20120307
    • queued and loaded objects
  • SAS.20120510
    • building new dvodb off of label SAStest.v4
      • cam stage is done, staticsky is in progress and I will run relphot -averages once done
    • waiting for PSPS to tell me when to start loading
  • LAP: I was supposed to load stacks, I did not yet because of problems on the ipp side
  • many discussions with Roy on many psps things, including: we need a way to track when to queue objects (when to run relphot -averages).
• dvodb
  • discovered the most recent merge of LAP was hung (since Apr 20).
    • Gene investigated - involved weirdness with out of memory - he debugged it
    • dvodb recovery: dvoverify says it's fine. It died mid-merge, so I need to merge the rest. I'm still in the process of making a backup of the affected directories before I do a region based dvomerge
• liason
  • transferred detrends used for SAS to rsync server. rediscovered that detselect is not useful (we need to make it useful), and I still have some unanswered questions about detrends.

Roy Henderson

• added Trac tickets for all outstanding PSVO bugs/enhancements
• PSVO:
  • introduced versioning (trac enhancement # 357)
    • version number is stored in the config file
    • online version of config means instances of PSVO can check for newer version
    • user prompted if new version is available, taken to webpage for download
  • new users can now view and accept PSPS terms and conditions from PSVO (trac enhancement # 355)
  • fixed bug where new users would still be connected to previous user's Derby Db (trac bug # 369)
  • added functionality to rename query tabs (trac enhancement # 361)
  • created new graphic for header panel as well as new Mac icon
  • new 'About' menu option from which users can check for a new version
  • work towards making mask generator and coord converter subclasses of more generic 'queryhelper' abstract class
• more developer documentation for PSVO:
  • notes on the new config file
  • detailed notes about how to make a release of PSVO
• fixed minor bug in ippToPsps where an incomplete config would break the metrics program
• more help with mailing-list handover. Rita is now in charge...
• helped Heather load MD4 objects

Mark Huber

• Czar Wednesday and Thursday, a little miscellaneous kicking LAP.
• Most of week spend getting up to speed on the STS fields and data to produce a refstack of 2011 exposures for MOPS (details to be added on ​http://svn.pan-starrs.ifa.hawaii.edu/trac/ipp/wiki/STS.refstack.20120510). Not the best, but maybe sufficient.
  • full set of 7 fields finished -- inspection shows some odd regions/skycells that may be problematic.
  • like with the MD refstacks, extra reftest runs were added with different inputs for quality and field coverage comparisons.
  • initial diffim tests run.
• Clean-up of ppStack past tests continues, about halfway done, in order to then return to alternative setting tests for the convolved stack target PSF.

Bill Sweeney

• Continued to work on the Kron magnitude measurements in psphot. Verified that we can obtain flux measurements consistent with SExtractor if we get the radius right. Performed a set of experiments with various recipe values to help us decide what the configuration should be.
• Lots of time was working on visualization and measurement tools as opposed to the code.
• Implemented a function to add and subtract a smoothed version of a model for a source.

Chris Waters

• Ghosts: Finished ghost modeling, with new version that correctly masks the majority of ghost reflections.
• Queued new SAS2 processing.
• Restarted LAP with new sequence id (seq_id = 10) at 2hr RA.
• Stacking: Looked at the stack quality in SAS2, and began thinking about rejection with boosted variances.
• AAS Poster work.
