Continuing effort has been made on ionogram reduction and data smoothing for use in a Hamiltonian ray tracing program which uses Haselgroves equations. Emphasis in this work has been placed on analog to digital as well as digital to hybrid compatibility. Power losses due to refraction and inverse square law spreading have been computed using a single ray approach. The method is fully described. Ray tracing has been done both with and without magnetic field. Comparison of these results led to the discovery that the magnetic field has a pronounced effect on the ray path even at frequencies much greater than 15 MHz when the path traveled is north-south, or along magnetic field lines. Tabulated results and the underlying factors in the argument are presented. Author
