GCN Circular 25094

The LIGO Scientific Collaboration and the Virgo Collaboration report:

We have conducted further analysis of the LIGO and Virgo data around
the time of the compact binary coalescence (CBC) candidate S190630ag
(GCN 24922
Not found
 
 
). Parameter estimation has been performed using
LALInference [1] and a new sky map, LALInference.offline.fits.gz,
distributed via GCN Notice, is available for retrieval from the
GraceDB event page:

https://gracedb.ligo.org/superevents/S190630ag

LALInference.offline.fits.gz is the preferred sky map at this time.
The 90% credible region is 1483 deg2. Marginalized over the whole sky,
the a posteriori luminosity distance estimate is 926 � 259 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
