Abstract:

We analyze the new mid-infrared maps of NGC 6946 for variations in the color ratio fo the 7-to-15µm emission. Our preliminary findings are that this mid-infrared color is remarkably constant between arms and inter-arm regions, and as a function of radius in the disk, excluding the nuclear region.
