Sampling 3D distances of individual stars from the cluster centre. a) Three cumulative radial cluster mass profiles with different EFF profile parameters; distances sampled with rnd_r = 0.6 are shown for each profile. b) 3D distance sampling result for log(M/M_⊙) = 5.0 cluster. c) and d) Two different log(M/M_⊙) = 3.0 cluster generations. In the case of low-mass clusters, the stellar spatial distribution exhibits significant stochastic effects. Red lines in b)-d) mark a distance sampling probability density function dM(< r)/dr.
