摘要
We study the statistics of isolated maxima and minima in the regions of three contrasting spots in the WMAP7 ILC data. A non-Gaussianity of signal distribution is detected in these regions. We demonstrate that non-Gaussian properties are related to the appearance of low harmonics (a"" a parts per thousand currency sign20). Possible reasons of this non-Gaussianity are discussed.
