The LIGO Scientific Collaboration and the Virgo Collaboration report:
We have conducted further analysis of the LIGO Livingston Observatory
(L1) data around the time of the compact binary merger (CBC) candidate
S190910h (GCN Circular 25707).
Parameter estimation has been performed using LALInference [1] and a new
sky map, LALInference.fits.gz, distributed via GCN Notice, is available
for retrieval from the GraceDB event page:
https://gracedb.ligo.org/superevents/S190910h
For the LALInference.fits.gz sky map, the 90% credible region is 24264
deg2. Marginalized over the whole sky, the a posteriori luminosity
distance estimate is 230 +/- 88 Mpc (a posteriori mean +/- standard
deviation).
For further information about analysis methodology and the contents of
this alert, refer to the LIGO/Virgo Public Alerts User Guide
