Comparison between our adopted parameters and the literature compilation. The standard deviation and mean of the differences are written and the corresponding curve is shown. The number of clipped observations compared to the total number of literature values is presented in the lower right corner of each of the panels. The colour of the points relates to T_eff; the size of the points to [Fe/H], and giants and dwarfs (logg limit 3.0) are indicated by diamonds and circles, respectively. In the T_eff and logg panels, two and four outliers, respectively, are not shown (various types of stars).
