Comparison of the average radial profiles (based on ten realisations of our models with 2.4k stars) of the projected models of segregated (blue) and non-segregated clusters (red) with the real ONC (black). In several time frames, we show two mass groups: m ≥ 5 M_⊙ (solid line) and m <  5 M_⊙ (dashed line). The corresponding statistic for each group can be found in Fig. 7, with the comparison even beyond the age of the ONC.
