A new method for analyzing the inhomogeneity in the microwave background maps, based on the behaviour of the angular power spectrum is proposed. We represent the change in the variance of the power spectrum of the hemisphere background signal in the form of a new map, which characterises the homogeneity (heterogeneity) in the background to second order. We use this method of analysis of the WMAP signal for maps with a resolution L<100. As a result, we detected the asymmetry of the ILC signal connected with the eclipse coordinate system, and it is also observed for the signal channel data in WMAP.
