Based on the relevant available data, the distributions of masses and apparent magnitudes of stars belonging to globular star clusters are simulated. The simulations are aimed at examining the influence of the mass-segregation phenomenon on the surface-density profile. It is found that a minor correction should be introduced in order to infer the profile of the surface density from that of the surface brightness.
