Notes. We listed: i) the V magnitude, BV, VK color-indexes, and their references (Ref. Phot., see below); ii) the parallax (π), its uncertainty (σπ), and the references (Ref. π, see below); iii) the stellar masses; iv) the number of spectra used in the analysis for a given target (N); vi) the median of the S-index and its dispersion (σS); vii) the median of the and its dispersion (); viii) the rotation period derived from Eq. (12); and ix) the averaged S/N in the violet and red bands.
