Differences between input and output gravities and temperatures across the HR diagram. The small black dots locate the XSL data according to our initial parameters, derived from the optical absorption line spectra using ULySS+MILES (Arentsen et al. 2019). The larger dots locate the same XSL data using the best-fit parameters obtained from the global comparison of the empirical spectra (UVB+VIS+NIR) with GSL models, reddened as necessary, at R = 3000. In the left panel color codes the differences in log(g) betweenthe two estimates; in the right panel it codes the differences in T_eff.
