P.A. Evans (U. Leicester) reports,
The bayestar.fits.gz,0 GW skymap has been convolved with the 2MPZ galaxy catalogue (Bilicki et al., ApJS, 210, 9),
using the method described in Evans et al (2016, MNRAS, 462, 1591*), to identify
a ranked list of potential host galaxies of the LVC trigger S200213t. This galaxy ranking
method accounts for the (line-of-sight dependent) completeness of 2MPZ, GW probability,
and the overlap between P(D) functions for the GW event and the individual galaxies.
In total 8952 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/S200213t/galaxies
