This RFC is for updates to the DPDD to bring it in line with current DRP plans
It removes reference to Multifit and multi-epoch fitting, clarifies plans for producing and serving coadds, and the current status of the approach to computing photometric redshifts.
These updates also require updates to the DMSR LSE-61. The corresponding DMSR requirements are proposed in
RFC-709. These 2 documents should be issued together to maintain consistency between the DMSR and DPDD
