TITLE: GCN CIRCULAR NUMBER: 38397 SUBJECT: LIGO/Virgo/KAGRA S241130n: Updated Sky localization DATE: 24/11/30 20:02:05 GMT FROM: Elise Sänger at Max Planck Institute for Gravitational Physics (AEI Potsdam) <elise.sanger@ligo.org> The LIGO Scientific Collaboration, the Virgo Collaboration, and the KAGRA Collaboration report: We have conducted further analysis of the LIGO Hanford Observatory (H1), LIGO Livingston Observatory (L1), and Virgo Observatory (V1) data around the time of the compact binary merger (CBC) candidate S241130n (GCN Circular 38391). Parameter estimation has been performed using Bilby [1] and a new sky map, Bilby.offline0.multiorder.fits,0, distributed via GCN Notice, is available for retrieval from the GraceDB event page: https://gracedb.ligo.org/superevents/S241130n For the Bilby.offline0.multiorder.fits,0 sky map, the 90% credible region is 302 deg2. Marginalized over the whole sky, the a posteriori luminosity distance estimate is 1790 +/- 518 Mpc (a posteriori mean +/- standard deviation).
