Notes. ^(a)As stated earlier in the text, regarding the clusters γ Vel, NGC 2547 and NGC 2451 A and B, we directly used the selections obtained by several studies listed in Table 1. ^(b)References for the mean cluster proper motions (pmra and pmdec) and parallaxes: (1) Kuhn et al. (2019); (2) Wright et al. (2019); (3) López Martí et al. (2013); (4) Cantat-Gaudin et al. (2018); (5) Kounkel & Covey (2019). ^(c)Final selection only consists of two members, final fit is not possible. ^(d)The 2σ membership interval for this cluster has been obtained after excluding a large contaminant population in the middle of the distribution, as detailed in Appendix A.
