TITLE: GCN CIRCULAR NUMBER: 25968 SUBJECT: LIGO/Virgo S190930s: Updated Sky Localization DATE: 19/10/07 13:23:42 GMT FROM: Olivier Minazzoli at LIGO Virgo Collaboration The LIGO Scientific Collaboration and the Virgo Collaboration report: We have conducted further analysis of the data from LIGO Hanford Observatory (H1) and LIGO Livingston Observatory (L1) around the time of the compact binary merger (CBC) candidate S190930s (GCN Circular 25871). Parameter estimation has been performed using LALInference [1] and a new sky map, LALInference.fits.gz,0, distributed via GCN Notice, is available for retrieval from the GraceDB event page: https://gracedb.ligo.org/superevents/S190930s The preferred sky map at this time is LALInference.fits.gz,0. The 90% credible region is 1748 deg2. Marginalized over the whole sky, the a posteriori luminosity distance estimate is 709 +/- 191 Mpc (a posteriori mean +/- standard deviation).
