Population distributions for primary mass (m₁, top panel) and mass ratio (q, bottom panel) using the COMPACTNESS PEAKS model for BBH mergers scaled by the fraction of events in the BH_L Peak (blue), BH_H Peak (pink), and POWER LAW (black) components. The solid curve is the median of the distribution and the shaded regions represent the 90% credible interval. The dashed line represents the median of the distribution for the MULTI PEAK model, which has the same mass ratio distribution for all components.
