• Precursor processing (AP team):
  • Eric Bellm completeness and purity tests of HSC-COSMOS:
    • followup: purity (Zooniverse):

      • edge flags vs. human edge labels: latter are at edges, as expected; former are all over in CCD coordinates, which is  weird
        • followup Slack discussion identified the issue: edge flags are set both on EDGE and NO_DATA pixels, and pixels which are saturated in all input images of the coadd are excluded with NO_DATA set.
      • nondetections: PSF Flux measurements show +/- 5 sigma detections, but aperture flux measurement doesn't.  Science looks like noise so this probably points to a narrow variance plane issue being caught up in PSF model

          for further followup.
      • both have obvious next steps to dig in and investigate 
  • Kenneth Herner / Ian Sullivan : diffim sprint configurations
    • PREOPS-630.  made best and middle-third seeing templates.
      • best seeing templates
      • preconvolve best seeing
      • default middle seeing
      • convolve science with the middle-third seeing template
        • least successful right now–large numbers of excess negative sources
      • Ian Sullivan : next step is to restrict analysis to the science images we are interested (e.g., science seeing better than template)
  • Meredith Rawls : Work-in-progress for getting HiTS working in gen3 with fakes and multi-tract processing
    • showing off the pipeline stages for this
    • single-CCD completeness plot, for now
• SITCOM team updates (Andrew Connolly  et al.):
  • Krzysztof Suberlak showing donut detection & Zernike estimation on AuxTel real data
  • also thinking about how to use in-focus images to seed fits of out-of-focus images. 
  • some AuxTel pointing issues have been resolved
  • Zeljko: do you have the piston from the telescope?  Andy: yes.  We're trying to work out the mirror collimation errors though
• PreOps V&V (Colin Slater ): 
  • schematic plan for DP0.2
    • w40 weekly frozen.  Processing team now running a set of precursors at IDF
    • V&V then will start validating single-frame, so processing team can start single-frame processing while V&V does coadds/diffim
• Review CI (https://chronograf-demo.lsst.codes/):
  • bump in the object count metrics due to DM-30465
  • very modest improvement in gen2 vs gen3 difference?
  • memory usage jumped on subsequent config tweak (not currently annotated)
    •  Ian Sullivan investigate metrics change due to DM-30465 25 Oct 2021 
• Next meetings (all at 4pm Pacific):
  • November 1
• AOB
  • John Parejko merged a command-line Zooniverse cutouts code
