Fig. 2


Density of RAVE stars with S/N ≥ 20 in the (Teff,log g) plane together with Padova isochrones for ages 3   Gyr (solid) and 9   Gyr (dashed). The colours indicate calibrated metallicities:  [M/H] =  −1 red;  [M/H] =  −0.6 yellow;  [M/H] =  −0.2 green;  [M/H] = 0 light blue;  [M/H] = 0.1 dark blue. The top row shows parameters from the VDR2 pipeline, while the lower row is for the VDR3 pipeline. In each row stars are grouped by metallicity, with the highest metallicities on the right. Note that in several panels, in the temperature range 6000 ≤ Teff ≤ 7000 the density of stars is high below the lowest isochrone. This anomaly is most pronounced in the lower row.
