Notes. Magnitudes and membership data from literature: probability of membership from proper motion, and classification of the star from radial velocity. We list the used instrument and the S/N of the spectra, and the obtained parameters from our spectroscopic analysis. [Fe/H] and ξ are from EW. ID numbers are from WEBDA. Proper motion membershipprobability from McNamara et al. (1977). References for classification (from radial velocity): (a)Cantat-Gaudin et al. (2014b)/Tautvaišienė et al. (2015), (b) Mathieu et al. (1986), and (c) Mermilliod et al. (2008) (M: member, SM: single member).
