Mid-infrared flux density ratio maps of NGC 6872. The maps in each wave band were cross-convolved with Gaussian representations of the point spread functions before division to mitigate light scattering effects. North is up and east is to the left. Mid-infrared color magnitude scales for the maps are (upper) [8.0] − [3.6] = 0.30 mag (blue), 2.27 mag (cyan), 2.80 mag (green), 3.24 mag (yellow), 3.55 mag (orange), 3.72 mag (red); (middle) [8.0] − [5.8] = 0.35 mag (blue), 1.11 mag (cyan), 1.42 mag (green), 1.70 mag (yellow), 1.86 mag (orange), 1.96 mag (red); (lower) blue (green) correspond ([5.8] − [8.0])_nonstellar = 2.1 (blue), 2.7 mag (green).
