TITLE: GCN CIRCULAR NUMBER: 36796 SUBJECT: LIGO/Virgo/KAGRA S240630t: Updated Sky localization DATE: 24/06/30 17:06:41 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 S240630t (GCN Circular 36794). 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/S240630t For the Bilby.multiorder.fits,0 sky map, the 90% credible region is 670 deg2. Marginalized over the whole sky, the a posteriori luminosity distance estimate is 3161 +/- 841 Mpc (a posteriori mean +/- standard deviation).
