Comparison of the two continuum models when applied to both the Orion Bar and NGC7469. The PDR pack was applied to the full wavelength range, with different continuum configurations as labeled. For the Orion Bar DF1 template spectrum, the main differences occur near 7.7, 13, and 18 μm. Regardless of the continuum used, the fitted attenuation is zero. For the NGC7469 SF2 spectrum, using the classic continuum results in zero attenuation, while the alternate continuum results in an attenuation of τ_9.7 = 1.5, which flattens out the silicate emission features. A zoomed in view and residuals of the DF1 (alternate continuum) and SF2 (classic continuum) fits are shown in Figs. 5 and 6.
