The LIGO Scientific Collaboration, the Virgo Collaboration, and the KAGRA Collaboration report:
We have conducted further analysis of the LIGO Livingston Observatory (L1) and Virgo Observatory (V1) data around the time of the compact binary merger (CBC) candidate S241101ee (GCN Circular 38036). 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/S241101ee
For the Bilby.multiorder.fits,0 sky map, the 90% credible region is 7670 deg2. Marginalized over the whole sky, the a posteriori luminosity distance estimate is 2160 +/- 695 Mpc (a posteriori mean +/- standard deviation).
