• Detection batches from last week loaded successfully. A relief.
  • able to test new, fast DetectionCalib table with PSVO
  • work to confirm that we have the same calibrated magnitude in PSPS as in the original IPP smf files

• Stack loading:
  • issue with NULL xPos and yPos values in StackDetection: was failing load
  • discovered that deep stacks can have duplicate objIDs and NULL flux values in psf table, thus explaining some previous issues
  • power-cut on monday. Hassles getting datastore back up, loading all the stuff processed the night before
  • discovered hundreds of nightly stacks with 0.0 EXPTIME, thus screwing up flux calculations
    • gpc1 query kindly supplied by Bill, but highlighted that a proportion of the previous stacks had non-zero, but incorrect, EXPTIME
    • changed code to use Bill's query, and reloaded everything
  • dupe objID confusions in deep stacks - ok in detection table, NOT in object table. Reloaded all deep stacks AGAIN
  • merge failed on Friday: ID we are using for stackDetectID is not unique. Need to add stack ID to primary key as a temporary fix.

• PSVO
  • discussions and testing of PSVO with query builder
  • made MOPSSchema class for query builder to use
  • slow queries now passed straight to TOPCAT, only first 1000 rows shown in table
  • many other minor changes
