Save downloaded skymaps? #51

Closed martinjohndyer closed 8 months ago

martinjohndyer commented 3 years ago

Since the issue raised in #36 we now force the download of the skymap for each event, but we actually don't store them anywhere (they will go to a temporary location based on astropy.utils.data.download_file). Perhaps it would be useful to download and store the skymaps for future reference, for instance #37 could use that.

Cross ref to https://github.com/GOTO-OBS/goto-obsdb/issues/53, which includes suggestions for storing event details in the ObsDB. Based on today's technicon with the file transfer from La Palma to Warwick we could store a hash of the skymap in the database for a quick lookup to see if the file has changed for #37, but I'd still say keeping the skymaps stored somewhere would be handy (actually we also store raw VOEvent XMLs already, which is arguably less useful).

Skymaps are saved in the alert database as of #71.
