Notes. (a)For γ Vel, NGC 2547 and NGC 2451 A and B, we used the selections listed in Table 1. (b)For these clusters, the final mean [Fe/H] values deviate more appreciably from the literature values. (c)We could not find any prior measurements from the literature for these clusters. (d)In the individual notes of Appendix A we also list the number of stars that we accepted as robust members despite deviating from these 3σ intervals. (e)Final selection only consists of two members, final fit is not possible.
