Notes

Merlin Fisher-Levine

• “Back in the zone”.
• Had an interesting debugging session with Ian Sullivan on astrometry issues.
  • Matching the AuxTel exposures with Gaia is not super-straightforward.
  • Some edge cases apparently succeeded, but in fact the majority are failing.
  • Tried to cut down the reference catalog selection, but this is not straightforward.
  • We can do magnitude cuts in the task config, but it's not clear if that requires the input image to be photometrically calibrated.
  • Maybe able to use built-in filtering in the ReferenceObjectLoader to address this.
  • Not clear that this will resolve all the problems, but it's a good way to start.
• Continuing with AuxTel data reduction this week.
• Discussing gain measurement on AuxTel with Nick Mondrik (Stubbs' grad student).
  • Using PTC code on AuxTel. Finding interesting screwy effects.
  • DM, Nick, eotest disagree on basic image statistics (mean, median, etc).
    • Merlin Fisher-Levine  will ticket this when he properly understands the problem.

Christopher Waters

• Crosstalk rework done; waiting for an RFC.
• Now back to DM-21212.
  • Fighting bugs; hoping to get it back into re-review this week.
• Talking with Eric Charles from SLAC/Camera about making eotest work with the stack.
  • See if eotest is useful for us, see if ip_isr is useful for them.
  • Iterating with Eric to come up with an end goal.
  • Worried about duplicating code.
  • Merlin is worried that this is a black hole of finding bugs in eotest and the lack of known-truth.
  • Agreed that Chris should chat to Eric about this, but avoid getting drawn into spending much time on this until a really concrete goal has been determined.
• Should file an RFC to add ci_cpp to lsst_distrib.

Andrés Alejandro Plazas Malagón

• Working on DM-24556 (defect normalization).
  • Current implementation broke some tests in cp_pipe; Andrés Alejandro Plazas Malagón will work on fixing them up.
• Crosstalk in AuxTel (DM-24531).
  • Can still see some residual crosstalk.
  • SLAC matrix does better than we can do.
    • Andrés Alejandro Plazas Malagón  will follow up with them to understand where their data came from.
  • Hoping to get better data rather than change our algorithm.
  • Thinking about non-linear crosstalk for the future.
• Coming next:
  • Fixing up normalized defects.
  • DM-20070,
