  • Meeting recorder -  Arun Kannawadi (last 6 meetings were:  Clare, Lee, Colin, Jim, Keith, Fred, Nate) 
  • Announcements
  • Review Action items from last month
    • Segfaults is now fixed (thanks Eli!)
    • Proper motion from Gaia makes visit-level plots a bit worse, but we don't see them in the meeting. Not much effect on the coadd plots. - Clare
    • Stellar locus width metrics had a huge jump early March, and dropped some 3 days ago. - Jeff.
      • Could be a combination of two events - GBDES and aperture corrections. We know what changes they correspond to, but don't know why. No tickets jump out. - Yusra.
      • Sky Object placement could also affect the dynamic detection (Stellar Locus Width is measured on coadds) - Lauren
      • File a ticket to investigate stellar locus RC2_SUBSET sensitivity March 8, March 10, April 14. (and remmeber action from last time to  add numbers of stars used in the fit as a metric itself) add label =  "pipelines-support" (DM-38733)
      • We need to understand why things got worse, since we always try to improve - Jim. 
      • Cannot fetch logs from butler, because these are from nightly CI jobs and need to fetch them from Jenkins Artifacts. - Jeff. 
  • Processing Status
    • w_2023_11 - DM-38360
    • Stalled because of BPS bugs
    • Segfault in ip_diffim, and Eli fixed it.
    • Starting with CM means we found a whole lot of CM bugs that we now fixed.
    • Aperture corrections failing on detectors 102, 103 [is expected]. We allow some aperture corrections to fail, and we don't know why Kron is not among them - Eli
    • Even in weekly 15, we got same failures involving aperture corrections - Orion. Orion should also complain about pipeline failures. Don't know why dispatch failed. Any help in the coming days is appreciated.
    • We can't have 3 pipelines failures every RC2 by default. Check that they won't be included in the coadds per new requirements. Then figure out how to handle. File a ticket.
  • Review the w_2023_11/ DM-38360 rerun:
    • Recall history:
      • w12: psfex
      • w16: piff  (bad size residuals)
      • w20: finalizeCharacterize (bad apcorr configs → bad stellar locus)
      • w22: lanczos11 + apcorr configs (better stellar locus and size residuals approx equivalent to psfEx!
      • w24: PIFF kernelSize to 25. new scarlet lite storage.
      • w28: attempt at fixing measure failures:  DM-35722 - Getting issue details... STATUS
      • w32: First RC2 at SLAC. subtractImages compatibility mode on
      • w36: subtractImages Compatibility mode off
      • w40: 
      • w44:
      • w48: 9697/7 succeeds, extra subtractImage failures gone
      • w03: Issues with using finalize characterize PSFs downstream. 
      • w07: ip_diffim. Cannot find plugin (fixed on DM-38209) run with ticket branch. Issues with finalize characterize downstream gone. 
      • w11: detectAndMeasure seg faults (fixed with hours to spare for w15) 
    • Chronograf, plot-navigator review of _11
      • Typing doesn't fetch the relevant plot - Lauren
      • Eric says Jim signed off on the naming, but it seems very noisy.
      • Jointcal in w07 → GBDES in w11, they look basically the same in astrometry plots barring scatter. - Clare
  • w_2023_09 DC2:
  • What do we expect next time 
    • Sky object placement (pseudorandom) 
    • Whole run in CM. - Orion
    • Solving the mystery that happened in 12,13,14
  • Other notes:
  • AOB:

LM: a few observations while poking around at the plots:

  • w07 on the left and w11 on the right. Need to improve formatting. Nothing earth shattering otherwise - Lauren
  • skyObjectHist plot labels are fixed (but we may need to rethink the numerical formatting...):
  • Something is amiss with the new rho stats plots - Arun Kannawadi will create a ticket to investigate this:

analysis_drp version:

analysis_tools version:

  • [stellar locus plots are still "wrong" (see DM-35336 - Getting issue details... STATUS  for details ) ]
