The LIGO Scientific Collaboration and the Virgo Collaboration report:
We have re-analyzed LIGO and Virgo data around the time of the compact
binary coalescence (CBC) candidate S190510g (GCN 24442). 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/S190510g
For the LALInference.fits.gz skymap, the 90% credible region is 1166 deg2.
Marginalized over the whole sky, the a posteriori luminosity distance
estimate is 227 +/- 92 Mpc (a posteriori mean +/- standard deviation).
This is the preferred sky map at this time.
For further information about analysis methodology and the contents of
this alert, refer to the LIGO/Virgo Public Alerts User Guide
