P.A. Evans (U. Leicester) reports,
The bayestar.fits.gz,2 GW skymap circulated with the "Initial" skymap notice differs somewhat
from the earlier skymap (see GCN Circ. 26759 for a list of the skymaps available). Thus the
earlier list of possible hosts galaxies (GCN Circ. 26756) is no longer appropriate and has been revised.
In total 9311 galaxies with P>10^-5 have been identified. The most probable 20 are listed below,
a full list and more details are available at: https://www.swift.ac.uk/LVC/83/galaxies
This page will automatically update after any new skymap is released, and the galaxy list for any skymap
can be selected.
