Tables describing the evolution of stellar models with initial masses equal to 120, 85, 60, 40, 25, 20, and 15 solar masses are given for metallicities Z = 0.002, 0.005, 0.020, and 0.040. The evolution is followed from the zero-age sequence to the end of the central carbon-burning phase. The various model data are given here at corresponding evolutionary stages in each set of models. Together with up-to-date physical ingredients, these models are based on new opacity tables, which account for the fact that, at low metallicities, the abundances of several elements have nonsolar ratios with respect to iron. The present tables are a summary of more than 40,000 individual stellar models.
