LIGO/Virgo/KAGRA S231028bg: Updated Sky localization

We have conducted further analysis of the LIGO Hanford Observatory (H1) and LIGO Livingston Observatory (L1) data around the time of the compact binary merger (CBC) candidate S231028bg (GCN Circular 34895). Parameter estimation has been performed using Bilby [1] and a new sky map, Bilby.multiorder.fits,0, distributed via GCN Notice, is available for retrieval from the GraceDB event page: https://gracedb.ligo.org/superevents/S231028bg For the Bilby.multiorder.fits,0 sky map, the 90% credible region is 1207 deg2. Marginalized over the whole sky, the a posteriori luminosity distance estimate is 4221 +/- 923 Mpc (a posteriori mean +/- standard deviation).
