Notes. Intensities are derived using SPIRIT. The second column lists the central wavelength of each feature. PAH complexes include the following sub-components: 7.42, 7.55, 7.61, and 7.82 μm features (PAH 7.7); 8.50 and 8.61 μm (PAH 8.6); 11.20 and 11.26 μm (PAH 11.3); 12.60 and 12.77 μm (PAH 12.7); 16.45, 17.04, and 17.375 μm (PAH 17). We only list the lines used in this work.
