STEPAR results for the Gaia benchmark stars plotted against the literature values taken from Heiter et al. (2015b), with updated values from Jofré et al. (2019). Upper panels: one-to-one correspondence, whereas bottom panels: absolute differences. Using the values in Table 3, the dashed black lines in the upper panels correspond to a one-to-one relationship, shifted following the average differences in each parameter, whereas in the bottom panels they are centred on the average differences. The dashed red lines in all panels correspond to a margin of 120 K, 0.30 dex, and 0.09 dex in T_eff, log g, and [Fe/H], respectively, according to the σ values found in the differences in each parameter.
