Zoom-ins on continuum-subtracted template spectra (not corrected for calibration issues, i.e. $F_v^{\text{obs}.}$ in Eq. B.2), compared with the MIRI-MRS spectrum of the absolute calibration star 10 Lac divided by the model for this star (green). The positions of identified AIB features are shown with vertical lines. The bracketed regions indicate excess absorption or emission artifacts due to incomplete flux calibration (Appendix B).
