Stochastic stellar mass sampling of individual cluster stars. a) Cumulative mass distribution Ξ(m) in the range from 0.1 to 100 M_⊙ (black line) and its application for stellar mass sampling (blue dashed line). b) Histogram – log(M/M_⊙) = 5.0 cluster mass function matches a theoretical IMF with high accuracy – weak stochastic effects. c) and d) Histograms – two different generations of log(M/M_⊙) = 2.5 cluster – low-mass clusters exhibit significant mass function stochasticity in the tail of massive stars. b-d) The orange lines represent the IMF ξ(m) for an infinite mass cluster (probability density function).
