Scientific paper

We compare the observed colour-magnitude diagrams (CMD) and the main sequence luminosity functions (LFs) of four Large Magellanic Cloud (LMC) star clusters namely, NGC 1711, NGC 2004, NGC 2164 and NGC 2214 with the synthetic ones derived from the stellar evolutionary models. Four different types of stellar evolutionary models have been used for comparison. The comparison of the features of the observed CMDs with the synthetic ones favour the overshoot models from Bressan et al. (1993). The synthetic integrated luminosity functions from the models can be matched with the observed ones by varying the value of mass function slopes. In order to constrain the models from the comparison of the synthetic ILFs with the observed ones, reliable estimates of mass function slope and binary fraction are desired.
