Notes. The SEDs in this Table were obtained fitting the same Planck and IRAS data as in Pl-MBB (see Sect. 2). The scatter is the largest at 143 and 217 GHz due to the statistical noise in the Planck data, and at 60 μm due to variations in fPDR.

(a)

Bolometric dust emission per unit AV computed from the DL fit.

(b)

The specific intensities for the Planck 217 and 143 bands were not used to constrain the DL model.

(c)

Dispersion of the specific intensities normalized by ΣLd computed over sky pixels within a given Umin bin. We list the mean standard deviation for each frequency since the measured dispersions are similar for the different Umin bins.
