Attendees:


Notes:

  • Christopher Waters 
    • Photodiode linearity work
      • How will this be working on the mountain?
      • Is everything being ingested?
    • Documentation
    • Crosstalk coefficients.
      • Priority for this week.
    • Metrics into ISR
      • Needs reviewer.
      • Missing metrics.
      • DM metrics of image quality.
        • Add to exposure statistics table/visit summary table?
  • Robert Lupton 
    • Postgres running at summit, but schema and ownership is unclear.
      • Can be loaded from EFD
      • No owner at the moment to keep it moving
    • Afternoon calibration convergence.
    • LATISS: voltage changes/new calibrations.
      • Find out with Merlin
  • Agnès Ferté 
    • Other Rubin work.
    • More on lateral E-fields
      • 2D DECam corrections with Gary
      • Need to write metric for fit quality.
      • Do we want to remove this from flats only, or use the values to correct astrometric results?
      • Put sinusoidal signals in to identify issues.
      • Monochromatic flats are unclear at the moment, with no clear answer as to how many/how long the exposures will be.
      • Check that templates work on combined and raw flats
        • See what the metrics note about the different inputs.
        • See if things commute properly.
    • Calibpalooza ordering:
      • DM-36647
      • PP?
      • Do we need to add more mask bits.
  • Eli Rykoff 
    • Work with Patrick to identify how to do laser scans.
    • Dust spots
      • Focus?
      • Ask Patrick.
    • FGCM Using isolated stars
    • Antilogus and gain normalization
      • Agree that use the gain to switch to electrons/effective gain of 1.0
      • Nonlinearity plots show that we still have amp-level gain errors, which are more problematic.
      • Temperature dependent gain.
      • BF correction within 30 pixels of the edges
        • To first order, not a function of intensity
        • Should see it in flats
      • Centerline:
        • Bleed stop adds charge in the location that distorts things.
      • "Rabbit ears" is a new different time-varying effect.
        • Tearing effect, due to holes left in the device
        • Related to the amplifier locations
    • Not available next week due to Boston galactic reddening conference.
      • No progress in the last seven years.
