Comparison of model fits with different assumptions of filament inclination. The model assumes FWHM=0.5 pc and A_V = 1^mag and the CMM dust properties. Frames a-c show the fit residuals for the default model and frames e-g show the residuals when the filament is inclined 45 degrees with respect to POS. The corresponding scalings of the ISRF levels are given in frames b and f. Frame d shows the 250 μm optical depth for the default model, and frame h the optical depth in the inclined model relative to the default model.
