Notes. Column 1 lists the object name; Col. 2 the number of spectroscopic members; Col. 3 gives the number of spectroscopic members that have a match within 1″ in Gaia DR2; and Col. 4 is as before, but that have kinematic information in Gaia DR2; Col. 5 lists the number of spectroscopic members that passed our additional membership criteria (see text); in Col. 6 we provide the source of the spectroscopic catalogs. In Col. 6 we also mark the cases for which we derived the spectroscopic membership probability ourselves, next to the catalog where this was done: “Yν” when only l.o.s. velocities were used; “Yνg” or “YνMg” when the information on the star’s logνg or the near-IR Mg I line at 8806.8 Å were also taken into account. In Cols. 7 and 8 we list the distance modulus adopted and its source, respectively; we always add an error of 0.1 mag in quadrature to the error in distance modulus listed here to safeguard against underestimated systematic errors.
