Fig. 3
Low ℓ power spectra Sℓ (left panels) and Kℓ (right panels) calculated from smica and nilc foreground-cleaned Planck maps equipped with inpmask (first row) and valmask (second row). Tiny horizontal shifts have been used to avoid overlaps of symbols. The 1σ error bars (68.3% confidence level) are calculated from the power spectra of 1000 Gaussian maps.
