LIGO/Virgo S190707q: Updated sky localization
Abstract
We have conducted further analysis of the LIGO and Virgo data around the time of the compact binary coalescence (CBC) candidate S190707q (GCN 25012). 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/S190707q LALInference.offline.fits.gz is the preferred sky map at this time. The 90% credible region is 921 deg2. Marginalized over the whole sky, the a posteriori luminosity distance estimate is 781 ± 211 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 <https/emfollow.docs.ligo.org/userguide/>. [1] Veitch et al.
