Mid-IR spectral modelling of the nuclear regions of NGC 6552 (top panel) and NGC 7469 (bottom panel) using PAHFIT. The JWST/MRS rest-frame spectra and model fits correspond to the solid black and red lines. We show the continuum (solid brown lines) and the fitted PAH features (solid blue lines). The silicate feature in emission (solid green line) is included for the fit of NGC 7469.
