Zoom of the benchmark model spectrum including the astro-PAHs grain model (orange) and estimated uncertainties on the calculation (light orange filled region) in the JWST spectral range, overplotted on the NIRSpec-MIRI combined spectrum. Note the emission in the model is higher in the 8–10 microns, which may be related to an overestimate of the silicates stretching mode contribution in emission in this range. The astronomical PAHs emission from the HD97300 disc is also shown in order to delineate the astronomical PAHs spectral profiles observed in another disc.
