Maps showing the selected apertures. From left to right panels: NGC 5506, NCG 5728 and NGC 7172. Top panels: 6.2 μm PAH feature intensity map. The white contours are the 11.3 μm PAH emission on a logarithmic scale (same values as in bottom panels of Fig. 3). Bottom panels: [Ne II] 12.81 μm intensity map. North is up and east is to the left, and offsets are measured relative to the AGN. Black circles correspond with the extracted apertures.
