Modified upper tail probabilities (mUTP) obtained from the analyses of the filter coefficients as a function of the filter scale R for the Commander (red), NILC (orange), SEVEM (green), and SMICA (blue) sky maps. From left to right, the panels correspond to standard deviation, skewness, and kurtosis results, when determined using the SMHW (top), GAUSS (middle), and SSG84 (bottom) filters. The squares represent UTP values above 0.5, whereas circles represent UTP values below 0.5.
