Topics for discussion

• HiTS reprocessing (Meredith Rawls):
  • working on the excess detections due to background problem
• DES processing (Unknown User (emorganson)):
  • ops rehearsal last week: data transfer, (simulated) images were processed through SFP.  Main learning was about communication
  • New faster computers that will eventually go to Chile; Eric will run ap_pipe timing estimates on them for comparison: faster disk reads, more RAM, etc.
• ap_association (Unknown User (cmorrison)):
  
  • Chris is out this week
• DCR (Ian Sullivan ):
  • found & fixed bug when template is finer resolution than science .  Probably this didn't affect HiTS processing since unlike the DCR sims the spatial sampling of HITS science and data are the same
  • also wrote code to correctly calculate PSFs from DCR models
  • gets somewhat cleaner results now (e.g. in total number of sources) since deconvolution artifacts have decreased
• image differencing (Unknown User (gkovacs) ):
  • worked on backlog tickets
  • wrote to Robert, who requested a short writeup with particular attention to preconvolution
  • thinking some about interaction between polynomial modifications to the kernel
• Review CI (https://chronograf-demo.lsst.codes/):
  • Minor decrease (→ improvement?) in # of unassociated DIAObjects, which we associate with DM-19660
  • gradual (?!) improvement in runtime; Jenkins has migrated to faster machines at NCSA, but it's not an obvious step function
• AOB
  • Ian requests another DCR run of DECam HiTS–Meredith will teach him to fish
  • Meredith: needs an expert (maybe Yusra) to evaluate a possible config change. other option is to fix ip_diffim 
    • Unknown User (gkovacs) is assigned to investigate
