Notes. (a)References for the E(B–V) reddening adopted from Jackson et al. (2022) for all clusters. (b)GES studies that reference the clusters and/or study them without taking membership analysis primarily into account. (c)Updated cluster ages using Gaia data, as listed by Bossini et al. (2019).
References. For the cluster ages, reddening and distances shown here we chose the most recent or most robust estimates for each cluster, but several other studies are further cited here, and age estimates are additionally briefly discussed in the individual notes of Appendix A: (1) Rigliaco et al.
