Asymptotic directions and vertical cutoff rigidities for selected cosmic-ray stations as calculated using the International Geomagnetic Reference Field model appropriate for Epoch 1975. 0. Environmental research papers

Technical Report ·
OSTI ID:7184507
Tables of asymptotic directions and vertical cutoff rigidities for a selected set of cosmic-ray stations are presented. These values were obtained by the integration of vertically incident cosmic-ray trajectories through the International Geomagnetic Reference Field model adjusted for a 1975.0 Epoch. The table of asymptotic directions contains the asymptotic latitudes and longitudes that specify the direction of approach from interplanetary space of a cosmic-ray particle. These asymptotic directions are given for specific rigidities above the main cone cutoff rigidity for each station, and at 0.01 GV rigidity intervals throughout the penumbra. Maps of the asymptotic directions for each station are also included. The table of vertical cutoff rigidities contains the geographic coordinates and L value of each cosmic-ray station together with the main cone cutoff rigidity, the Stormer cutoff rigidity, and the effective cutoff rigidity.
