cWB skymap not found on the "public alerts" GraceDB page
The root cause of this is probably outside GraceDB and I apologize if this has already been discussed elsewhere -- or is being addressed at the moment. For the recent cWB public alert, https://gracedb.ligo.org/superevents/public/O3/ displays
S200114f (...) No public skymap image found.
likely because the Bayestar sky maps are labelled "cWB" instead of "bayestar": https://gracedb.ligo.org/apiweb/superevents/S200114f/files/cWB.fits.gz. While fixing the naming convention for the cWB skymaps (that may be on purpose), a test could be added to GraceDB to look for cWB.fits.gz if bayestar.fits.gz is not found.
