The resulting re-estimate of the background model yields a\n\nFAR (False Alarm Rate) of 1 in 3.6 years compared to 1 in 37 years initially\n\nreported in GCN 24442.\n\n\nUsing the updated background model, the classification of the event,\n\nin order of descending probability, is estimated to be:\n\nTerrestrial (58%), BNS (42%), NSBH (<1%), BBH (<1%), or MassGap (<1%).\n\n\nFurther analysis of the event is ongoing. Updates will be provided\n\nas and when available.\n\n\nFor further information about analysis methodology and the contents of\n\nthis alert, refer to the LIGO/Virgo Public Alerts User Guide\n\n<https://emfollow.docs.ligo.org/userguide/>.",
