IPP Progress Report for the week 2012-05-28 - 2012-06-01

This week, with telescope operations off line for a bit, we decided to dump and re-ingest the full Nebulous database. The dump was smooth, though somewhat slow, but the re-ingest was much slower than expected. We decided to switch to the replicated server as the main database engine while the main server continued to ingest. This gives us a (apparently successful) real-world test of our fall over process.

• provided some text contributions to Henry Hsieh's MBC proposal to NASA
• merged my branch with DVO-related dev work and psphot/psModules model variance work into the trunk
• discovered that the 'haveUbercal' and 'haveSynth' photometry flags in the dvo 3pi database were not set correctly, so re-ran relphot to ensure these were set
• re-generated all-sky 2mass comparison plots and basic relphot stats plots
• re-generated the all-sky tables for Mark Bolden & published to the dvodist server

Mark Huber

• Czar Tuesday and Friday

• dealing with MD09.GR0 reprocessing and new refstack

Bill Sweeney

• Reported results of psphotStack photometry to DRAVG. Many questions.
  • The data shows that the psphotStack measurements based on the morphology of objects like the Kron measurements and the model fits show better results when using the unconvolved stacks.
  • There is an offset between SDSS stripe 82 psf magnitudes and psphotStack when a Gaussian psf model is used. A smaller offset results using the PS_MODEL_PS1_V1
  • The scatter in the kron magnitudes appears to be larger than with psphot. This turned out to be due to a bug in the code causing sources with bad moments to be measured.
• Implemented and tested a feature that limits the kron integration area based on the surface brigthness of the source. With this change the kron radii are much better behaved.
• Based on all of the above we have updated the psphot recipes and code and created a new operational tag. We are ready for SAStest.v5
• Note: worked half of last Saturday and Memorial Day. Took holiday on Friday instead.
