The mid-infrared profiles of the Corona Australis filament. The offsets are the same as in Fig. 5. In addition to the Spitzer 3.6 μm and 4.5 μm data (blue and lines, respectively, and the right hand y-axis) the figure includes the profiles for the scattered light in the H and Ks bands (cyan and magenta lines, left hand axis) and the A_V derived from the Herschel observations (black dashed line, left axis).
