Comparison of PHOENIX-ACES (blue) and PHOENIX-SESAM (red) models for a selection of lines. The parameters of the models are Teff = 3500 K, log g = 5.0 dex, and [Fe/H] = 0.0 dex. The models are broadened corresponding to the spectral resolution in the VIS (R ≈ 94 600) and NIR (R ≈ 80 500) channel. For each wavelength region the residual between the two models are shown.
