Caption: Solid points denote the gravitational-wave (GW) events from the O4 run (scheduled between May 2023 and ~December 2024) and faint points denote the events from runs O1-O3. BNS/NSBH implies either Binary neutron star (BNS) or that there is ambiguity between BNS and neutron star-black hole (NSBH) merger classification (e.g. MassGap). NSBH/BBH implies either NSBH or binary black hole merger (BBH). Hover over the data points to view Event IDs, merger classifications, and false alarm rates (FARs in units of per year). Only FAR<1 per year events are considered here.
