Radial profile of the normalized PAH emission in four spectral bands for select sources. Sources are ordered column-wise, and the PAH bands are ordered row-wise and are color-coded (from 7.9 μm in the uppermost row to 12.6 μm in the bottom row). The filled area represents the ±1σ error range around the median value of the emission amplitude posterior distribution of the relevant PAH template (see Appendix C). The orientation of the spatial dimension (parallel to the long axis of the slit) is denoted in the upper-right corner of the uppermost panel. Additionally, the dashed gray line is the high-S/N synthesized PSF (Appendix F), plotted for reference.
