Notes. – The cluster names and their coordinates are listed in Columns 1–3. The heliocentric distance is shown in the fourth column, while the proper motions are shown in Columns 5 and 6. The values listed in Columns 1–6 are taken from the literature works indicated in Section 1. The number of member stars for each cluster in this work are reported in the seventh column. The RV¯Mathematical equation: $\overline {{\rm{RV}}} $ is shown in in the eighth column, while the intrinsic velocity dispersion calculated in this work is shown in the ninth column. The literature tidal radius is listed in the tenth column, converted to parsecs. In particular, we adopted the tidal radius from Saroon et al. (2024) for CWNU 4193 and FSR 1700 and from Garro et al. (2022c) for Garro 02. In the case of BH 140 cluster, we derived its tidal radius from Gaia DR3 data (see Appendix D). Finally, the last column shows the estimated mass for each cluster.
