Notes. The age of every cluster has been taken from the WEBDA database. ( * )Ages derived by our group in this paper (for NGC 6649, NGC 6664 and Be 55) or in previous works (Alonso-Santiago et al. 2017, 2019b, for NGC 6067 and NGC 2345, respectively). ( * *)According to Cantat-Gaudin et al. (2018), Cepheids QZ Nor (NGC 6067) and RU Sct (Trumpler 35) are not considered cluster members and, therefore, to maintain homogeneity, they have not been taken into account in this table. However, the cluster membership of QZ Nor should not be questioned based on the evidence from Majaess et al. (2013), who, unlike Cantat-Gaudin et al. (2018), conducted a comprehensive investigation exclusively devoted to clarify this issue.
