| Resumo: | We present the results on the age estimates of 11 Small Magellanic Cloud (SMC) clusters obtained for the first time from CCD Washington CT1T2 photometry. CMD cluster features - mainly cluster RCs and MSTOs - turn out to be identificable when performing annular extractions around their respective centres, once they were cleaned from field star contamination. We estimated ages for the cluster sample using the δT1 index, and metallicities from the SGB technique. The resultant ages and metallicities for the control clusters are in excellent agreement with those previously published, thus confirming our present age/metallicity scale. We also confirmed the ages and metallicities derived for the clusters by fitting theoretical isochrones. |
