TITLE: GCN CIRCULAR NUMBER: 42306 SUBJECT: LIGO/Virgo/KAGRA S251014cn: Updated Sky localization DATE: 25/10/16 07:51:43 GMT FROM: Nihar.Gupte@aei.mpg.de
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 S251014cn (GCN Circular 42255. Parameter estimation has been performed using Bilby [1] and a new sky map, Bilby.multiorder.fits,0, distributed via GCN and SCiMMA notices, is available for retrieval from the GraceDB event page:
https://gracedb.ligo.org/superevents/S251014cn
For the Bilby.multiorder.fits,0 sky map, the 90% credible region is 172 deg2. Marginalized over the whole sky, the a posteriori luminosity distance estimate is 607 +/- 164 Mpc (a posteriori mean +/- standard deviation).
