Notes. In order we list the observed central wavelength of each PAH complex (λ_PAH), the wavelength interval used for its extraction (Δλ_PAH), the blue and red continuum windows ( $Δ λ_{cont}^{blue}$ $Mathematical equation: $ \Delta\lambda_{\mathrm{cont}}^{\mathrm{blue}} $$ , $Δ λ_{cont}^{red}$ $Mathematical equation: $ \Delta\lambda_{\mathrm{cont}}^{\mathrm{red}} $$ ), and any overlapping gas-phase emission lines. PAH 16.5 μm is usually included in the 17 μm complex.
