Notes. The lower part of the table includes the stars from Bensby et al. (2010c)†.
Column 2 gives the spectroscopic temperature; Col. 3 the stellar mass (inferred from ischrones); Col. 4 the luminosity (inferred from isochrones), Col. 5 the stellar age (inferred from isochrones); Cols. 6 and 7 the 1-sigma lower and upper age limits; Col. 8 the “spectroscopic” colours, based on the colour-[Fe/H]- calibrations by Casagrande et al. (2010); Col. 9 the absolute V magnitude based on the spectroscopic stellar parameters; Cols. 10 and 11 the 1-sigma lower and upper limits on MV; Col. 12 the absolute I magnitude based on spectroscopic stellar parameters; Col. 13 the absolute I magnitude based on microlensing techniques; Col. 14 the (V − I)0 colour based on microlensing techniques; Col. 15 the inferred effective temperatures using the colour-[Fe/H]- calibrations by Casagrande et al. (2010); Col. 16 Comments: DR stands for differential reddening.
