Book Description
Tables of vertical cutoff rigidities calculated using the trajectory-tracing technique are given for two epochs of the geomagnetic field. The Finch and Leaton magnetic field coefficients were used for Epoch 1955, and the Jensen and Cain coefficients were used for Epoch 1960. Each table includes 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. Data for approximately 2900 locations on the earth are presented.

Book Description
Tables of non-vertical cutoff rigidities calculated using the trajectory-tracing technique are given for 76 various locations. These calculations were made using the Finch and Leaton magnetic field coefficients appropriate for Epoch 1955. Each table includes the geographic coordinates and L value of each location, the zenith and azimuth angles for which the calculations were made, and the main cone cutoff rigidity, the Stormer cutoff rigidity, and the effective cutoff rigidity.

Book Description
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.

Book Description
Tables of asymptotic directions and vertical cutoff rigidities for a five degree by fifteen degree world grid are presented. These values were obtained by the integration of vertically incident cosmic-ray trajectories through the International Geomagnetic Reference Field with time derivatives applied so that the coefficients form a quiescent model of the geomagnetic field for Epoch 1975.0. 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 Stoermer cutoff rigidity, and the effective cutoff rigidity.

Book Description
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 Finch and Leaton (Epoch 1955) quiescent model of the geomagnetic field. 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 symptotic directions for each station are 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 Stoermer cutoff rigidity, and the effective cutoff rigidity.

Book Description
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.

Book Description
Tables of cosmic-ray cutoff rigidities using the trajectory-tracing technique are given for three epochs of the geomagnetic field. These values have been determined utilizing the International Geomagnetic Reference Field with time derivatives applied so that the coefficients for the field model are appropriate for the following epochs: 1965.0, 1970.0, and 1975.0. Each table includes the geographic coordinates and L value of each location together with the main cutoff rigidity, the Stormer cutoff rigidity, and the effective cutoff rigidity. The altitude for which each set of values was calculated is also given. Tables for both vertical and non-vertical directions are included. These cutoff rigidity values are supplemental to those published in previous AFGL reports. In addition, minor corrections to previously published values are also included.
