Agenda:
- 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: 
- 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
for details 
) ]
