Fig. 3
Left column: 3.6, 4.5, and 8.0 μm images of the central 80 × 80 pc2 of the GC. The middle column shows the diffuse background resulting after point-source subtraction from each image. The right column shows, from top to bottom, the diffuse 3.6 μm emission (top middle) minus 0.03 times the 8.0 μm image (bottom left), the diffuse 4.5 μm emission (centre) minus 0.04 times the 8.0 μm image (bottom left), the 8.0 μm image (bottom left) minus diffuse emission at 8.0 μm (bottom middle). The green circle in the middle panel indicates a region with strong PAH emission in the 4.5 μm image.
