Cumulative density function of the peak distribution for the SMICA CMB temperature map. The top row shows the peak CDF for maps filtered with a GAUSS kernel of 40′ FWHM. The bottom row shows the corresponding peak CDF for an SSG84 kernel of 800′ FWHM. The spectral shape parameter γ (see Eq. (27)) is the best-fit value for the simulated ensemble, as indicated by the cyan circle in Fig. 11. Similar results are obtained for the other component-separation methods.
