OSTI ID:7184502
Tables of asymptotic directions and vertical cutoff rigidities for a five degree by fifteen degree world grid are presented in this report. These values were obtained by the integration of vertically incident cosmic-ray trajectories through the International Geomagnetic Reference Field for Epoch 1965.0. The table of asymptotic directions contains the asymptotic latitudes and longitudes which specify the direction of approach, from interplanetary space, of a cosmic-ray particle. These asymptotic directions are given for each grid point for specific rigidities above the main cone cutoff rigidity. The table of vertical cutoff rigidities contains the geographic coordinates and L value of each location together with the main cone cutoff rigidity, the Stormer cutoff rigidity, and the effective cutoff rigidity.
