| Popis: | A test of the Gaussianity of the background signal in the zones located symmetrically with respect to the Galactic equator is proposed. The test is based on the analysis of the dominating harmonics in symmetric zones and the distribution of the correlation coefficients as a function of the number of selected multipole. Zones located symmetrically in the Galactic and ecliptical coordinate systems are chosen and analyzed for the presence of an antisymmetric signal. Nongaussian properties are found in the distribution of the correlation coefficients for several zones |
