Model Color-Magnitude Diagrams for [ITAL]Hubble Space Telescope[/ITAL] Observations of Local Group Dwarf Galaxies

In this Letter, we discuss a method to conduct a quantitative study of the star formation history (SFH) of Local Group (LG) galaxies using Hubble Space Telescope (HST) data. This method has proved to be successful in the analysis of the SFH of the same kind of galaxies using ground-based observations. It is based on the comparison of observed CMDs with a set of model CMDs. The latter are computed assuming different evolutionary scenarios and include a detailed simulation of observational effects.
