Notes. Values for [Fe/H] and mass of each cluster, and the number of stars in each chromosome map subpopulation are also listed. Metallicities for NGC 288 and NGC 2808 are from Carretta et al. (2009a). The tabulated [Fe/H] for M 3 is from Cohen & Meléndez (2005). The total cluster mass log Mtot is from McLaughlin & van der Marel (2005).
