Scientific paper

The main-sequence LFs are derived for three fields at different radial distances from the center of the globular cluster M30. It is found that the LFs become flatter with decreasing radius. The observed radial dependence of the slope of the LF is compared with the predictions of mass segregation from the multi-mass component King (1966) models computed by Pryor et al. (1986). The models are shown to be consistent within the errors with an equipartition model with a global mass function slope of x = 0.9, confirming the validity of the mass segregation corrections of Pryor et al.
