TITLE: GCN CIRCULAR NUMBER: 34213 SUBJECT: LIGO/Virgo/KAGRA S230709bi: Updated Sky localization DATE: 23/07/13 17:38:51 GMT FROM: Colm Talbot at MIT <talbotcolm@gmail.com> The LIGO Scientific Collaboration, the Virgo Collaboration, and the KAGRA Collaboration report: We have conducted further offline analysis of the LIGO Hanford Observatory (H1) and LIGO Livingston Observatory (L1) data around the time of the compact binary merger (CBC) candidate S230709bi (GCN Circular 34175). 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/S230709bi For the Bilby.multiorder.fits,0 sky map, the 90% credible region is 2644 deg2. Marginalized over the whole sky, the a posteriori luminosity distance estimate is 4364 +/- 1585 Mpc (a posteriori mean +/- standard deviation).
