Notes. In the first three columns (after the cluster identification) we reproduce the results published in Paper II to facilitate comparison. In the following three columns the results for E(B − V) the extinction, distance to the cluster and log (Age) the logarithm of the age (in years) obtained in this work are presented. The reference codes given in last column are the same as given in Table 1. See the text for error estimate details.
