J. Ralph Johler; Carlene M. Mellecker

Abstract: The subject computer programs are described and the FORTRAN source decks are Listed. The physical problem solved by the computer program is described. It allows an anisotropic ionospheric model, and variations in the model along the propagation path. The input and output of a sample case are listed.

Disclaimer: Certain commercial equipment, components, and software may be identified in this report to specify adequately the technical aspects of the reported results. In no case does such identification imply recommendation or endorsement by the National Telecommunications and Information Administration, nor does it imply that the equipment or software identified is necessarily the best available for the particular application or uses.
