Abstract content

The method of the analysis of data on vertical rigidities of cosmic rays cutoff is described. The essence of the method consists in the fact, that both the experimental data and the calculation results are described in the form of change of their value relative to the values related to IGRF. The value of these relative changes quite certainly depends on the rigidity itself and on the level of geomagnetic field disturbance (the Kp-index). Systematic distinctions between the experimental data and the results of calculations by Tsyganenko-89’s magnetosphere model in the region of low rigidities (R < 0.5 GV) are revealed.
