Notes. Values in the bottom part of the table were derived in this work. (a)Zero-point correction from Lindegren et al. (2021) applied. (b)The role of PARSEC isochrones for the R⋆ estimate is to transform absolute magnitudes into luminosity via bolometric correction tables provided with the evolutionary grids (Marigo et al. 2017).
