TITLE: GCN CIRCULAR NUMBER: 37429 SUBJECT: LIGO/Virgo/KAGRA S240908bs: Updated Sky localization DATE: 24/09/08 15:42:31 GMT FROM: Christopher P L Berry at LVK Collaboration <christopher.berry@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 S240908bs (GCN Circular 37426). 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/S240908bs For the Bilby.multiorder.fits,0 sky map, the 90% credible region is 74 deg2. Marginalized over the whole sky, the a posteriori luminosity distance estimate is 3350 +/- 1130 Mpc (a posteriori mean +/- standard deviation).
