“…Since light nuclei at a given energy are less deviated in magnetic fields than heavier ones it means that the source of the anomaly is in the direction of the maximum. The analysis of the stability of this result [12] showed that accidental errors of the S parameter do not change the position of the anomaly but reduce the hight of the maximum χ 2 /J , which depends on the error values. If the errors are asymmetric in azimuth angles of the laboratory coordinate system, which rotates with the Earth, then they induce the appearence of an additional maximum in the direction of the Earth's rotation axis ('World's Pole').…”

“…An additional study [12] showed that showers from the maximum region are initiated by PCR with a lighter mass composition ('young' EAS) compared with those from the opposite direction at PeV energies. Since light nuclei at a given energy are less deviated in magnetic fields than heavier ones it means that the source of the anomaly is in the direction of the maximum.…”

“…The main idea of the method [6] is the following: we take directions ( 0 , b 0 ) in the galactic coordinate system and build a cone around each of them. Its width angle θ (or H 0 = cos θ ) is selected in such a way that it divides all registered particles in two sets with an equal number of particles in both of them -inside and outside the cone: n in = n out .…”

Abstract. On the basis of experimental data obtained in the knee energy region with the GAMMA array an anomaly has been found in the mass composition of primary cosmic rays coming from the region of the VELA cluster. We used an original difference method which has high sensitivity, stability against accidental experimental errors and the possibility to separate anomalies connected with the laboratory coordinate system from anomalies observed in the celestial coordinates. The multiple scattering of the charged particles in the galactic magnetic fields makes it possible to study regions of the sky outside the direct visibility of the array.

“…The difference method for the test of the knee models at ∼ 3 × 10 15 eV was suggested in [12]. The difference (more accurately -the diffusion-difference) method for the analysis of experimental data, assuming the diffusive character of the PCR propagation in the Galaxy, is as follows.…”

The methodical properties of the original difference method for the search of the anisotropy at the knee region of the primary cosmic radiation energy spectrum are analyzed. The main feature of the suggested method is a study of the difference in the EAS characteristics in different directions but not their intensity. It is shown that the method is stable to the random experimental errors and allows to separate the anomalies related to the laboratory coordinate system from the anomalies in the celestial coordinates. The method uses multiple scattering of the charge particles in the Galaxy magnetic fields to study the whole celestial sphere including the regions outside of the line of sight of the installation.
