Three clusters of the SMC from ACS/WFC HST archive data: NGC 265, K 29 and NGC 290 and their field population
Abstract
Aims:We determine the age, metallicity and initial mass function of three clusters, namely
Methods: We make use of ACS/WFC HST archive data. For the clusters, the age and metallicity are derived fitting the integrated luminosity function with single synthetic stellar population by means of the χ2 minimization. For the companion fields, the history of star formation is derived using the χ2 minimization together with the downhill-simplex method.
Results: For the clusters we find the following ages and metallicities:
