- Precursor processing (Meredith Rawls ):
- DM-29422: gen3+bps HSC Cosmos run
- sample of random 50 diasource cutouts
- Zeljko points out that many of the HiTS sample alerts had single pixels with very negative values–we seem to see similar effects here
- sky plot with 3+ good DIASources looks pretty good–only a little bright star and edge structure. With all good DIASources it's a bit worse
- using a larger list of bad flags–but still majority of the
- plots per visit still showing some per-CCD and edge troubles
- seems like next step is starting to explore where the weird effects appear in spatial positions/flags/look at cutouts, etc.
- equivalent HiTS processing awaiting port into shared gen3 repo
- DM-29422: gen3+bps HSC Cosmos run
- SITCOM team updates (Andrew Connolly et al.):
- Krzysztof Suberlak shared work on ComCam simulations.
- Simulations of donuts (phosim) using ComCam and LSSTCam, processed using stack Gen 3 pipeline
- Also processing the equivalent in-focus images
- Note that crosstalk is not yet turned on
- Do not need special camera mappers anymore
- Krzysztof Suberlak shared work on ComCam simulations.
- PreOps V&V (Colin Slater ):
- nothing today
- Review CI (https://chronograf-demo.lsst.codes/):
- Observed difference in diaSource to direct source ratio is probably due to diffim variance scaling in DECam, not clear where the difference comes from in HSC
- Likely somewhere in single frame measurement
- For HSC Gen 3, there are differences in the number of sources detected on the calexp and the calexps themselves have differences at the pixel level
- Yusra: in DRP the Gen 2 and Gen 3 calexps for HSC are now bitwise identical, the fix was changing how the calibs are read in. Lauren MacArthur would be able to explain more.

- There's also a dump bump in the ratio of DIASources to science sources on 4/25-4/27 in both cameras in both gens that we don't have annotated...
