Nuclear (top) and circumnuclear (bottom) averaged spectra obtained from the four channels of MIRI–MRS. The two regions of extraction are delimited by a 1.3″-radius circle (24 pc), as shown on the small inset image (continuum map at 17 μm). This aperture corresponds to 2×FWHM of the PSF at the wavelength of 0–0 S(1) line. The identified emission lines are labeled in different colors. Brackets are omitted from the spectroscopic notation for visual clarity. The H₂ rotational lines are labeled in yellow. The main PAH features are indicated with gray vertical bands. Zoomed-in views of the spectra on the different MRS channels are displayed in Appendix C, Figure C.1.
