Posterior distributions of the Hubble constant and the parameters describing the BBH mass distribution for the Flexible-BBH, PS-paired, MLTP-paired, and MLTP models. The four peaks correspond to the maxima of the cubic spline functions for the Flexible-BBH and PS-paired models, as illustrated in Appendix C.1.
