TITLE: GCN CIRCULAR NUMBER: 38394 SUBJECT: LIGO/Virgo/KAGRA S241127aj: Updated Sky localization DATE: 24/11/30 14:56:01 GMT FROM: ethan.payne@ligo.org The LIGO Scientific Collaboration, the Virgo Collaboration, and the KAGRA Collaboration report: We have conducted additional 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 S241127aj (GCN Circular 38361). Parameter estimation has been performed using Bilby [1] and a new sky map, Bilby.offline1.multiorder.fits,0, distributed via GCN Notice, is available for retrieval from the GraceDB event page: https://gracedb.ligo.org/superevents/S241127aj For the Bilby.offline1.multiorder.fits,0 sky map, the 90% credible region is 53 deg2. Marginalized over the whole sky, the a posteriori luminosity distance estimate is 1050 +/- 67 Mpc (a posteriori mean +/- standard deviation).
