I was asked to open a PR about this so there's an official record somewhere. This is just a request to modify AP to only label single IFO gracedb uploads with ADVREQ if they
- Pass the alert FAR threshold and
- are found in coincidence with a GRB
It looks like Raven already updates event logs with information about possible coincidences (see e.g. https://gracedb.ligo.org/events/view/T276080, under "External Coincidence"), so I believe the only change needed on the approval processor side will be differentiating between single and double IFO candidates, looking for this information from raven if a single ifo candidate, and then a conditional that describes when to apply the advreq label.
