This book was released on 1975 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: An updated five by fifteen degree world grid of trajectory-derived vertical cutoff rigidities for Epochs 1965 and 1975 has been calculated using the International Geomagnetic Reference Field with time derivatives applied for a 1975.0 Epoch. A comparison of these vertical cutoff rigidities with those calculated for Epoch 1955.0 shows that whereas minor changes in the cutoff rigidities (or about equal 0.20 GV) occur in many areas of the world over this 20-year interval, major changes ( 0.60 GV) occur in the Central and Southern Atlantic Ocean area and over the Central and South American land masses. While the changes in the Southern Hemisphere are primarily decreases in the vertical cutoff rigidities, there is an area in the Northern Hemisphere, principally in the Atlantic Ocean, where comparable increases in the vertical cutoff rigidities are calculated.

This book was released on 1982 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book excerpt: Tables of cosmic-ray cutoff rigidities using the trajectory-tracing technique are given for five 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: 1955.0, 1965.0, 1966.5, 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. Tables for both vertical and non-vertical directions are included, as well as a listing of the FORTRAN computer program used to calculate these values. (Author).

A. Shea and published by . This book was released on 1975 with total page 174 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 excerpt: 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.
