Fitting of the modelled line profiles. From top to bottom, the models PE-1, PE-2, and PE-3 are shown. Please note the different scaling on the y axis (flux) for each panel. For each model, we show the [OI] 0.63 µm (first row) and the o–H₂ 2.12 µm (second row) for five different inclinations (columns from left to right). Each panel shows the line profile with the model resolution (blue) convolved to a resolution of R = 50000 similar to the observations (black), and the fit (the NLVC) to the convolved profile (red solid line).
