DPDD incorrectly states "immediate" access to PPDB products

    Details

      Description

      Section 3.3 says:

      The described alert processing design relies on the “living” Level 1 database that contains the objects and sources detected on difference images. [...] As these get updated and added to, their updated contents becomes visible (query-able) immediately.

      This is inaccurate, as the database baseline requires users to access a replicated version of the PPDB, and the timescale for that replication is not yet decided. DMS-REQ-0004 requires that the nightly products be accessible in less than L1PublicT, which is currently 24 hours.

      I think it is generally expected we can replicate the database much faster than once per day, but I don't believe there's a solid number we can provide.

            I've summarized all references to L1PublicT in the Observatory and DM requirements on this Confluence page: https://confluence.lsstcorp.org/display/~gpdf/Requirements+referencing+L1PublicT .

            I've changed the tex to "within 24 hours" to match the DMSR for now, so we can include this in current batch of DPDD updates. I'll file a follow-on ticket in a minute to study if we can shorten that time lag.
