Note: the first column contains the number of stars, N, the next eight columns contain the designation, the cluster size, R, the number density in a sphere of a radius of 0.3 pc, $\rho _{{\rm TC}}$ (equivalent to the Trapezium Cluster in the ONC, see Sect. 2), and the three-dimensional velocity dispersion, $\sigma_{{\rm 3D}}$ , for the density-scaled and size-scaled models, respectively. The last three columns denote the median maximum stellar mass in each simulation, $m_{{\rm max}}^{{\rm med}}$ , the median maximum stellar mass for sorted sampling, $m_{{\rm max}}^{{\rm sort}}$ , and estimates from observational data, $m_{{\rm max}}^{{\rm obs}}$ , both taken from Fig. 7 of Weidner & Kroupa (2006).
