Summary for MD.PV3 (updates in progress)

• MediumDeepFields summary page -- quick links to all up to date refstacks
• MD.GR0 summary page -- summary of all reprocessing details and 2011/2012 refstacks and some deepstack samples
• MD.PV1 summary page -- the data set that PV2 update reprocessing is based on
• MD.PV2 summary page -- update type reprocessing

This is a summary of the MD.PV3 full pixel reprocessing. Start date and schedule TBD.

This processing will also involve other MD-like fields, including M31, STS and CNP. Criteria for the stacks and diffims are TBD. From Ken's talk at PS1SC@STSCI meeting in June 2014:

• stack
  • MDN -- night stack
  • MD0 -- seasonal reference stack
  • MDD -- deep stack
  • MDT -- iq stack
• diffims:
  • warp-stack (WS) -- (warp-ref)?? , (warp-deep)
  • stack-stack (SS) -- (night-ref)

Issues to address:

• disk space limiting
• chip-warp:
  • refcat oddities in field
  • background restore and masking for M31/STS -- test samples to be run
• stack
  • stack quality fault
  • night stack config, refstack edge loss
  • ref+deep stack input cuts
  • iq+ref+deep test stacks for CNP,M31,STS
• staticsky/skycal
  • zeropt recalib in skycal
  • stack photometry sky oddities
• diffim
  • verify similar photometry
  • verify similar detections/coverage (no sig loss on edges)
• full-forced photometry -- unknown, untested still

_Summary Status:_

• 10/1 start chip-warp for MD should be possible, STS+M31 sample should be possible

---

chip -- camera -- warp

Should be started ASAP, so that the warps are available for some early testing of the stacks and diffims.

Testing necessary for the M31, STS and CNP processing still.

---

stack

Order of operations important -- while deep stacks take 1.5 months or so to finish, night and seasonal reference stacks must be finished before diffims can be started. Lighter jobs like difference images and iq (even reference stacks) can be run along with the deep stacks for some fields.

Cannot start until both night and seasonal reference stacks finish.
