Synthetic spectra (top and bottom panels) and scattered-light images (middle panels) of our generic model at two different inclinations (grazing angle and edge-on). Images at 3.0 μm are shown with a logarithmic color scale. The squares correspond to the extraction zones in the edge of the disk (dashed blue line) and in the central point source (solid red line) with the associated spectra at different inclinations (between 60°and 90°). A spectrum of the lower nebula in the grazing-angle geometry is shown with a dashed green line in the top and bottom panels.
