The total (solid line), thermal (dotted line), scattered (dashed line), and primary source (dash-dotted line) emission are plotted. The left panel is a type 1 inclination (i = 0°), the right panel a type 2 inclination (i = 90°). The two vertical lines indicate the central wavelengths of the two dispersing prisms of the Gaia photometric instrument (integrated with the astrometric instrument), at 0.50 and 0.82 μm. The values of torus parameters are the same as taken in Fig. 3.
