Frequency dependence of the dust SED in intensity without AME (top), in polarization without synchrotron (middle), and the polarization fraction (bottom) for the four different combinations of dust models. The SEDs are plotted in units of KRJ and normalized to 1 at 353 GHz. The shaded areas represent 1σ (green), 2σ (yellow), and 3σ (grey) statistical uncertainty on the mean normalized polarization fraction. We used the mean spectra from the same 400 sky patches for both the intensity and polarization analysis.
