Notes. The HD number and the conventional stellar name for the three stars; the spectral type; the effective temperature derived from the spectroscopic approach reported in Takeda et al. (2005); the apparent V magnitude and the trigonometric parallax π in milliarcsecond, taken from the Hipparcos Catalog (ESA 1997); the absolute V magnitude, MV, derived from the π and V values; the bolometric correction obtained from the results reported in Alonso et al. (1995); stellar luminosity log (L/L) and L/L derived in Takeda et al. (2005) from MV and B.C.; stellar mass (in units of M) determined by L/L and Teff.
