Performance of the algorithm on GW events from the third LVK observing run (O3) (Abbott et al. 2023); abbott.2024. The X axis denotes the chirp mass inferred using LALInference (Veitch et al. 2015) parameter estimation and the Y axis represents masses predicted by our OCP algorithm. These estimations were made using an identical number of BAYESTAR simulations made with the actual O3 detector noise curves. Poor estimation in the low mass region can be attributed to variability in the stability of detector noise curves.
