Distribution of retention probability, with and without population weighted samples, computed from all the informative events in GWTC-2 as a function of the escape speed of the star cluster Vesc. The solid lines with markers show the median values while the shaded regions show the 90% credible intervals of the distributions. These curves are obtained without any assumptions about the cluster type or properties (besides being characterized by a single value, Vesc).
