Differential merger rate as a function of mass ratio (evaluated at z = 0.2) of the BROKEN POWER LAW + 2 PEAKS model (orange) and B-SPLINE model (blue). The fiducial POWER LAW + PEAK model from R. Abbott et al. (2023a) is included for comparison. Solid curves indicate posterior medians and the shaded (dashed) regions show 90% credible intervals.
