Component mass probability distribution comparisons. Component masses (left panel: BH; right panel: NS) probability distribution (red lines) for the fiducial model in Broekgaarden et al. (2021) used in this work and posterior predictive distributions (solid blue), 50% and 90% credible intervals (shaded blue) inferred from the population of four candidate BHNS events detected in GW with a FAR rate ≤1 yr⁻¹ (Biscoveanu et al. 2023).
