Fig. 8 ~ Continuum-subtracted infrared line emission spectra for a disc inclination of 45° and spectral resolution R = 3000 with varying mixing parameter α_mix. It is important to note the different scaling of the y-axis. Most visible spectral features are overlapping o-H₂O (blue) and p-H₂O (black) emission lines. A few other features emitted from other molecules and ions are annotated in one of the plots. Each molecular spectrum is first convolved with a Gaussian R = 3000 and then overplotted with a certain colour, but not co-added.
