Comparison between the EPINARBO and Lumba parameters against signal-to-noise (S/N) determined for Spec0 in the top row and Spec2 in the bottom row. Left to right: the panels compare spectroscopic Teff, spectrocopic/seismic log g, and spectroscopic [Fe/H], in turn, for UVES (red) and GIRAFFE (blue) spectra. Yellow circles are stars rejected by EPINARBO for inconsistent Fe I and Fe II abundances in Spec0. Central white circles (GIRAFFE) or white triangle (UVES) are stars rejected by EPINARBO for inconsistent Fe I and Fe II abundances in Spec2. The median and MAD of the difference is given for each.
