Time dependence of f_IC(m) for clusters of mass 400 M_⊙ starting with initial conditions for models ‘S’ (solid lines) and ‘M’ (dashed lines). The values of f_IC(m) for different stellar spectral types is shown by line colours. The fraction of all stars in clusters f_IC(M_ecl = 400 M_⊙) is shown by the black lines. The clusters orbit the galaxy at R_g = 8 kpc and they have metallicity of Z = 0.014.
