• PSPS
  • helped investigate with Sue why MDF frames have appeared in 3PI catalog
  • ippToPsps
    • finally finished refactoring all code to use new Fits class. Much cleaner now.
    • made a new class to encapsulate the initialization data, i.e. a clean OO interface to config data such as filterIDs, surveyIDs etc
    • new FitsGenerator class to encapsulate code for generating and populating FITS files
    • new Logger class that can write to stdout or log file, complete with debug, info and error levels. Also handles code timing.
    • added unit tests for stack batches and init batches, so a complete set.

• IPP
  • fixed issue with burntool plots showing 0 before midnight - just a UTC/HST issue

• Other
  • Responded to more Hungarian data access requests

• Finished testing and enable --continue mode in burntool to help catch up on registration if we fall behind.
• Identify a set of input warps for John Tonry to allow a comparison of IPP stacks vs. his independent stacking method. Have not finished comparisons of these stacks yet.
• Added a summit_id key to the summitExp, summitImfile, pzDownloadExp, pzDownloadImfile, newExp tables in the GPC1 database to speed the joins between these tables that are now required for the on-the-fly burntool and science processing we're now doing. Fixed miscellaneous bugs in this implementation as well.
• Examined STS exposures that had astrometry shifts for bright stars, and compared the stars to the burntool tables to see if damage due to burntool trail removal can explain the shifts. This does not appear to be the case, as astrometry from the same exposures without the burntool correction applied show the same sort of shifts.
