TITLE: GCN CIRCULAR NUMBER: 34788 SUBJECT: LIGO/Virgo/KAGRA S231001aq: Updated Sky localization DATE: 23/10/01 22:41:36 GMT FROM: Colm Talbot at University of Chicago <talbotcolm@gmail.com> The LIGO Scientific Collaboration, the Virgo Collaboration, and the KAGRA Collaboration report: We have conducted further analysis of the LIGO Hanford Observatory (H1) and LIGO Livingston Observatory (L1) data around the time of the compact binary merger (CBC) candidate S231001aq (GCN Circular 34785). 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/S231001aq For the Bilby.multiorder.fits,0 sky map, the 90% credible region is 3323 deg2. Marginalized over the whole sky, the a posteriori luminosity distance estimate is 2567 +/- 958 Mpc (a posteriori mean +/- standard deviation).
