Spatial distribution of the nominal 11.2 µm AIB, its two subcomponents at 11.207 µm and 11.25 µm, and maps of the 11.25/11.207, 11.25/11.2, and 11.207/11.2 ratios. In all maps, contours trace peak emission for the 11.0 µm AIB (white) and the 11.2 µm AIB (teal). The 11.25 µm map includes two sets of black contours at 0.516 10⁻⁵ and 1.25 10⁻⁵ W m⁻² sr⁻¹, which trace the smallest and largest regimes of emission strengths, respectively. The black contour on the 11.25/11.207 map, placed at the level of 0.8, surrounds the region of highest fractional emission. The rest of the map visualization conventions are described in Fig. 4.
