Notes. The parameter $N_{1\sigma}$ corresponds to the ratio of the number of stars in the decontaminated CMD with respect to the $1\sigma $ Poisson fluctuation measured in the observed CMD (Bica et al. 2008). Column 4: reddening in the cluster's central region. Column 6: $R_{\rm GC}$ calculated using $R_{\odot}=7.2$ kpc (Bica et al. 2006a) as the distance of the Sun to the Galactic centre. Uncertainties in $d_{\odot}$ and $R_{\rm GC}$ are of the order of 0.1 kpc.
