Resumen:
Abstract / We present a new determination of the age-metallicity relation for both Magellanic Clouds, estimatedthrough the homogeneous analysis of 239 observed star clusters. All clusters in our set were observed with theCT1 filters of the Washington photometric system. The Automated Stellar cluster Analysis package (ASteCA)was employed to derive the cluster?s fundamental parameters, in particular their ages and metallicities, throughan unassisted process. We find that our age-metallicity relations (AMRs) can not be fully matched to any ofthe estimations found in twelve previous works, and are better explained by a combination of several of them indifferent age intervals.
