GW190821_124821
Release: IAS-O3a
Event UID: GW190821_124821-v1
Names: GW190821_124821
GPS: 1250426919.9
UTC Time: 2019-08-21 12:48:21
Timeline: Query for segments
False-alarm rates are computed within each template bank; the search used 6 independent template banks. The reported SNR is that recovered by the search pipeline, which includes the LIGO Hanford and Livingston detectors only. See Olsen et al. (2022) for details.
