The KS-probability that the cumulative -distribution (left-hand figure) and -distribution (right-hand figure) obtained from the SDSS groups with four or more members is consistent with that obtained from MGRSs, as a function of f_BNC, the fraction of groups in which the most luminous satellite is brighter than the central galaxy (see text for details). The KS probabilities here are the means of log(P_KS) for 100 realizations with different random seeds.
