Apertures from which the five template spectra were extracted, overlayed on two slices of the MIRI MRS data cube. The horizontal axis is aligned with the y-coordinate of the IFU and the 9×1 mosaic strip. The blue component is the total flux at 11.3 µm (10⁴ MJy sr⁻¹), which contains some continuum, but mainly traces the 11.3 µm AIB and peaks in the atomic region. The red component highlights the locations of the dissociation fronts using the intensity of the H₂ S (1) line at 17.0 µm(10⁻³ erg s⁻¹ cm⁻² sr⁻¹). The two-dimensional color legend shows where one component (red and blue) or both components (dark purple) are bright.
