Logarithmically-scaled 3.28 μm PAH feature+continuum emission from Cen A. The data have been spatially smoothed by an 8 × 8 boxcar before log scaling. The bar in the lower right corner illustrates 200 pc at the distance to Cen A. The wedge to the right shows relative surface brightness levels. Note that the scale is the same as in Fig. 1.
