Examples of model fits where the LOS FWHM of the cloud is included as a free parameter. On each row, the first four frames show the 160–500 μm fit residuals, and the final frame on the right the map of the FWHM scaling (filament region only). The five rows correspond to the dust models COM, CMM, CMM-1, CMM-2, and AMMI, respectively. All calculations were done assuming A_V = 1^mag. The cyan contours show the outlines of the filament region, and the [10%, 90%] percentiles of the residual values are quoted in the frames (in units of percent).
