Illustration of the profile variability with the peak position of the 6.2 μm PAH band (top) and the relative peak surface brightness of the 7.8 μm component with respect to the 7.6 μm component (bottom). Black and white contours represent the integrated 6.2 μm PAH surface brightness and the H2 0–0 S(7) integrated surface brightness, respectively (Fig. A.1).
