Notes. Position (RA and DEC), ω̄, the astrometric information (proper motions and V_r) and photometry collected from Gaia eDR3 (Gaia Collaboration 2023). The column M-PROB lists the membership probability reported by Vasiliev & Baumgardt (2021) for each selected star. S/N lists the spectral signal-to-noise ratio, and the column POP lists the population generation (related discussion in Sect. 5.3).
