Top: the three SEDs in K_RJ units, normalized to 1 at 353 GHz, obtained by averaging, CMB corrected, CC coefficients from the fits with one (cyan circles), two (blue circles) and three templates (red circles). The uncertainties at each frequency are estimated using the subsets of Planck and WMAP data. Bottom: our SED from the three-template fit (red circles) is compared with the dust SED in Planck Collaboration Int. XII (2013) for the Gould Belt system (squares) and that at high latitude sky (inverted triangles) obtained applying the dust-Hi correlation analysis in Planck Collaboration Int. XVII (2014) to the full Planck mission data.
