Topics for discussion:

• HiTS reprocessing (Meredith Rawls)
  • summarizing recent work on , which spawned ,
  • Chris suggests that flags labeled "slot" may be more useful than eg using the pixel flags.
  • Ian suggests that DM-16544 is due to using PSF-matched coadds–any time the PSF convolution kernel touches a mask.  But that's to make the coadd, and the mask growing is happening in diffim.
  • Krzysztof says Yusra recommend convolvedTemplate=True last year for use with PsfMatched coadds. This is the default setting for ImageDifferenceTask, so we're currently using it implicitly.
• DES processing (Unknown User (emorganson))
• CI (Krzysztof Findeisen )
  • SQuaRE has been pushing forward on pushing ap_verify metrics to SQuASH.  But SQuASH assumes some metadata is present that isn't there.  Simon Krughoff has promised to fix it in
• DCR (Ian Sullivan )
  • gain matching code updated, new unit tests added, small bug found and fixed
  • responding to reviews on three tickets
  • Also made simulated test dataset with variable PSFs and ran through his code; doesn't work as well, as expect.  Extremely bad PSFs will drive model to divergence.  Just did a simple ~grid of PSF sizes.
  • what's it take to do HiTS?
    • Meredith Rawls has tried running this, but makeCoaddTempExp is hanging–needs investigation.
    • Ian Sullivan also has a smaller test DECam dataset
• ap_* development
  • Unknown User (cmorrison) PPDB seems to be running as expected, doing some quick checks to catch any null column handling issues.
  • wrapping up the ticket, then on to flags.
• AOB/table round
  • Eric thinking about matching to HiTS classified variables.  Chris suggests could instantiate DIAObject table with those objects and let them collect
