Top panel: merit function that was used to determine the best values, i.e. FWHM and constant offset of a Gauss function, to model the PSF of GRIS. Bottom panel: three spectral lines that are used in this study (black crosses) overplotted with the same lines from the FTS atlas (red) after they were convolved with the spectral PSF of GRIS.
