Attendees:


Notes:

  • Merlin Fisher-Levine 
    • Away Wednesday Afternoon through Monday Evening.
      • Keith is handling that part of the boot camp.
    • Camera team claims a "flush before every image".  Which possibly explains the short dark time, except we still see the features of long-idle.
      • Surface traps, etc.?  Camera retains some state?
      • Clean room tests with TS8 are all ITL chips.
      • Flushes and reads are different because of the timing of the serials.  There may be voltages that are inverted that aren't inverted on a flush.
    • Crosstalk and defects.
      • Crosstalk problems.
      • "Spicy corner" on LATISS, plus dust spots triggering defects for being too faint.
  • Christopher Waters 
    • Crosstalk woes.
    • Defect issues.
    • Brighter-fatter improvements by Yousuke and Alex have hit.
      • Let's have Arun look into this improvement?
      • Generate BFK for LATISS?
      • What does the HSC kernel look like?  What does a new one look like?
    • Linearity correction need denser PTC curve.
  • Eli Rykoff 
    • PTC issues with the initial points and KS test improvement were not the main problem.
      • An initial low-flux fit wasn't being calculated to identify the linear fit that should be used to identify outlier and post-turnoff points.
      • What does turn-off mean in an infinitely sampled PTC?  Is the pCTE limit something import?  Correlates with what seems like the saturation limit.
      • This depends on sampling, so we'll need better sampling?
  • Robert Lupton 
    • Thibault's calibration access errors.
    • Detector cleanup with potential camera access from the detector.
