SCs already known analysed in this work. For each of them this figure illustrates: Top Left: CMD of the candidate SC; Top Right: Hess diagram of the six fields used as representative of the local stellar field contamination; Bottom Left: CMD of the SC with stars colour coded according to their membership probability of being a cluster member along with the best fitting isochrone (solid line) and isochrones at log(t) = ±0.2 dex from the best one; Bottom Right: Spatial distribution of stars with respect to the SC centre. The solid circle marks the estimated SC radius.
