Request for skymap url in avro alerts (from Andy Howell)
From Andy: we're having an issue in HERMES with the LIGO alert format -- specifically it is not easy to figure out which Skymap goes with which alert in a machine-readable way. The proposed solution was for HERMES to create its own database, ingesting its own maps and to keep track of everything, which is way out of scope, and is not the right solution anyway. We just need to know like one bit of information that LVK knows and is not sending out in a convenient way. We asked for the gracedb URL to the skymap, which is in the VOEvent version of the alert, because this contains the information we need. So our possible workaround is to ingest those too. To go back to using an nonpreferred, non-Hop format is kind of crazy -- it is saying to users not to use this thing we've spent years building.
