Histograms of line parameters derived for HD-SPAT-SPEC and observations. Top left panel: line asymmetry. Top right panel: FWHM. Bottom left panel: equivalent width. Bottom right panel: line depth. The black line denotes the histogram of the relevant parameter for a given observational data set, the red line the one for the degraded simulation. Instrument and wavelength are denoted at the top of each panel.
