      I wrote in the LDM-151 redraft that decisions on how to build a reference catalog for use in DRP will depend on DM leadership clarifying the rules for reusing previous data release catalogs when processing the next one, and Robert Lupton commented:

      Is the need for this guidance captured formally anywhere?

      And hence I'm assigning this back to Robert Lupton, to identify uses cases where DRP would want to rely on previous data releases or AP results, and to consult with the rest of the DMLT on how to deal with any provenance concerns this would raise.

      Personally, I don't think we'll need a previous data release to make good-enough reference catalogs for PSF estimation and astrometric calibration, and I any help they'd provide in photometric calibration is outweighed by the provenance problems that'd raise. However, I do think we'll want to use the latest AP SSObject database in DRP MOPS. And I can't think of any other cases where this comes up.
