regrets:
Topics for discussion:
- Project updates (Eric Bellm , Ian Sullivan ):
- replan review is underway
- Pipelines Infrastructure (Krzysztof Findeisen ):
- working on getting fakes running in a way that will be compatible with later pipelines rearrangement–still just starting
- Precursor processing (Meredith Rawls, Kenneth Herner ):
- Meredith:
- still having some trouble with the last stage of DECam template building in gen3 shared repo
- is showing DC2 preliminary processing, small amount of g-band data
- there are some edge effects visible, and troubling overdensities
- is there dithering? we think so
- is the DDF included in this data/DP0.2? If not, are there are variables
- Ken: still stuck on problem w/ change since last weekly. otherwise busy with non-Rubin work
- QA meeting:
- fakes? Krzysztof is working on it this week but out next week, so we will see
- Meredith: nothing to show with HSC, DECam still debugging; just showed DC2 (on ap_pipe)
- Ken thinks he can work on DC2 in next couple weeks
- Meredith will try to show DECam data if she can get it working
- Ian: can we try to get cutouts with some metadata displayed alongside? (seeing, etc.)
- don't worry about making it elegant in the short term, can print it
- future topics:
- Ian: diffim unit tests? if results
- probably already overbooked for next QA meeting, but we could tag Gabor in the future for some show and tell
- also for next month: showing/discussing persisted likelihood images would be useful
- Meredith:
- Difference imaging algorithms (Unknown User (gkovacs), Ian Sullivan ):
- Gabor: showing a notebook trying to understand why simple positive/negative pixel swap metric changed when image order is swapped in ZOGY.
- problem was due to padding images with random noise (to avoid artificially biasing the variance low near the edges)
- found a bug that the metric was not actually calculated at source locations, but at random positions
- also sees grid-like (high-frequency) oscillation around zero–so the unit test failed
- fix is easy, already ready on a branch–seed the random number generator with the image rather than the image order
- Gabor: showing a notebook trying to understand why simple positive/negative pixel swap metric changed when image order is swapped in ZOGY.

sociation/SDM/fakes/astrometry (Unknown User (cmorrison)):- busy with DP0.2
- real-bogus (Eric Bellm, John Parejko ):
- no update
- Preops DP0.2 preparation (all):
- Chris:
- cleaning up simple association from DESC's dia_pipe, adding unit
- still waiting on review to merge main pipeline
- Meredith:
- draft writeup at "what I did" stage, unblocking Ken
- Ken to work on processing from here, with shadowing from John Parejko
- Chris:
- Review CI (https://chronograf-demo.lsst.codes/):
- nothing new. Chris believed he had identified some larger-than-floating point differences when reading from raws in - DM-29901Getting issue details... STATUS , which conflicts with Lauren's claim that HSC Gen2/Gen3 were bitwise identical coming out of SFM. We want to confirm Chris's work and ticket middleware if necessary.
- Review outstanding action items
- AOB
- Eric organizing SP weekly meetings in June, so topic suggestions welcome! (I have some ideas)
- several vacations this week and next
- Meredith still wondering where to put pipelines... DRP folks are putting stuff in obs_subaru that import from pipe_tasks/DRP.yaml.
