The method of correlation mapping on the full sphere is used to study the
properties of the ILC map, as well as the dust and synchrotron background
components. An anomalous correlation of the components with the ILC map in the
main plane and in the poles of the ecliptic and equatorial coordinate systems
was discovered. Apart from the bias, a dominant quadrupole contribution in the
power spectrum of the mosaic correlation maps was found in the pixel
correlation histogram. Various causes of the anomalous signal are discussed.Comment: 10 pages,11 figure
