log g vs. T_eff diagrams of Milky Way field stars in the metallicity range −0.2 < [Fe/H] < +0.2, available in iDR6. In the large panel we show the recommended stellar parameters from WG10 (in orange), while in the two upper panels we show the results of two individual nodes contributing to the final parameters for the MW field stars (different colours and symbols). Parsec isochrones (Bressan et al. 2012) at solar metallicity, and at three different ages are shown: 2 Gyr (in red), 5 Gyr (in black), 7 Gyr (in blue).
