Notes. p is the membership probability according to the analysis by Marigo et al. (2022) and Cantat-Gaudin & Anders (2020) (see text). The spectral types were taken from SIMBAD: https://simbad.unistra.fr/simbad/. The two stars marked with  appear in SIMBAD with an unknown spectral type. However, from their high resolution spectra obtained here we classified them as typical M-stars.
