Time dependence of the fraction of M (red line), F-K (orange), A (yellow), late B (green), early B (blue), and O (magenta) stars located in clusters for clusters with R_g = 8 kpc and Z = 0.014. The clusters are assumed to form with the ECMF of Eq. (4) with β = 2, M_ecl, min = 30 M_⊙, and M_ecl, max = 10⁴ M_⊙. At a given time, f_IC, pop(m) increases with stellar mass (apart from O stars), which is the result of dynamically induced mass segregation. The O stars are slightly depleted in clusters because of their dynamical ejections.
