Power spectrum of the residual map (map dust CMB) at 217 GHz obtained in the GASS field with different CMB templates: the 100 GHz Wiener-filtered map (red points); the 143  GHz Wiener-filtered map (blue points); and the SMICA map (orange points). These CMB maps are contaminated by both CIB anisotropies and shot noise. For the CIB measured using Wiener-filtered CMB maps, we can easily compute the correction to apply to recover the true CIB, using a model of the CIB anisotropies. Such corrected power spectra are shown with the dashed lines (using the CIB model from Planck Collaboration 2011RPlanck Collaboration XVIII 2011). They are only indicative, since the correction strongly depends on the CIB model.
