The empty circles show the stellar parameters before applying the empirical corrections from Bensby et al. (2014) and the coloured circles the parameters after the corrections. The values before and after the corrections are connected with solid lines. On average the effective temperatures change by −9 ± 12 K and the surface gravities by −0.01 ± 0.04. The colours represent [Fe/H], as shown by the colour bar on the right-hand side.
