Top: 857 GHz power spectra for the four different masks defined in the text. The dotted lines show the best-fit model defined by Eq. (9) fit to ℓ ≤ 500, capturing the Galactic dust. An estimate of the CIB power spectrum is shown in orange points (Planck Collaboration XVIII 2011). Bottom: power spectra after subtracting the Galactic dust model. The horizontal purple line shows a constant amplitude of 7 × 106μK2, which roughly describes the Planck CIB results.
