Cumulative density-function of the peak distributions for the SMICA temperature T (left) and reconstructed E-mode polarization (right) maps. Top row: peak CDF filtered with a GAUSS kernel of 120′ FWHM, bottom row: peak CDF filtered with the same kernel of 600′ FWHM. The spectral shape parameter γ (see Eq. (29)) is the best-fit value for the simulated ensemble, as indicated by the cyan circle in Fig. 15. No significant deviations from Gaussian expectations are observed. Similar results are obtained for other component-separation methods.
