Notes. RA and Dec are reported as in J2000 reference frame. Values in the bottom half of the table have been derived as part of this paper. (a) Zero-point correction from Lindegren et al. (2021) applied. (b)R⋆ is computed within the isochrone placement interpolation scheme as PARSEC isochrones convert stellar luminosity into absolute magnitudes via a series of bolometric correction tables built as explained in Marigo et al. (2017) and references therein.
