TITLE: GCN CIRCULAR NUMBER: 18851 SUBJECT: LIGO/Virgo G184098: Updated FAR estimate DATE: 16/01/11 10:20:22 GMT FROM: Marica Branchesi at LSC The LIGO Scientific Collaboration and Virgo report: We have completed offline calibration and re-analysis of the segment of data containing the gravitational-wave trigger G184098, which was first recovered on 2015-09-14 (GCN 18330, GCN 18388). We have calculated a revised false alarm rate based on four detection pipelines: the cWB (with and without BayesWave follow-up) and oLIB searches for un-modeled bursts plus the PyCBC and GSTLAL offline searches for compact binary coalescences of neutron stars and/or stellar-mass black holes. All four pipelines estimate that G184098 is more significant than one per hundred years.
