IPP Progress Report for the week 2012-10-29 - 2012-11-04

(Up to IPP Progress Reports)

Eugene Magnier

  • work on NSF proposals

Serge Chastel

  • Czar on Tue and Wed
  • Took care of data for mops tests
  • Slow progress with HTCondor (Note: the project has been renamed)

Heather Flewelling

  • vacation for a week - saw ps1 telescope and answered too many emails ...

Mark Huber

  • MD03 refstack for new season MD03.refstack.20121101
  • MD05 reprocessing for ubercal of pixels
  • investigation WS diffim PSF mag offset

Bill Sweeney

  • Learned how ipptopsps works. Modified the code for the new PSPS schema for SAS 10. The biggest change was to populate the StackDetection? and StackDetectionCalib? tables using calibrated values from DVO. Built test batches and started the loading process.

Chris Waters

  • Finished major work on the background stacking/projection cell products. Masks now correctly set bits, and ppBackground can be used to readd the stack background back to the image. Ran test of SAS g-filter data.
  • Czar for two days.
  • Studied WW and WS diffs sent to MOPS. After puzzling on the variance for some time, realized that the convolution direction on the WS diff was not correct. This led to an investigation of the convolution direction on the WW images, with the conclusion that the ppSub configuration was not doing what was assumed. A test of this (shown at http://svn.pan-starrs.ifa.hawaii.edu/trac/ipp/wiki/MOPS_diff_false_positives) illustrates that correctly setting the convolution direction results in better diffs. This likely also explains the odd jump in detection limits between the WW and WS diffs. Continuing tests on this topic, but the configuration files have been changed to do diff convolutions in the directions we assumed they had been done.
