Fit using the CMM dust model, FWHM = 0.5 pc, and A_V = 0 mag. The first row of frames shows the observations, the second row the predictions of the fitted RT model, and the third row the fit residuals. The actual fit used only 250–500 µm data. The data are plotted at the resolution of the used observations, but the contours in the bottom frames show the ±4% error levels (red and blue contours, respectively) when, for clarity, the data have been smoothed to 3 arcmin resolution.
