Fit of the SED to the five spectral windows available at 250, 350, 500, 1250, and 2000 μm at the peak emission when convolving and regridding all windows to the resolution of the 500 μm band. The error bars indicate the weights used in the fitting, which correspond to the uncertainties and noise associated with the data. The shadowed blue region show the 95% confidence intervals of the fitted parameters.
