Called by 'green.for'. Whole two-point rays are stored in files corresponding to individual elementary waves and the points of intersection with given surfaces are stored in files corresponding to individual surfaces. All whole rays are stored, not only two-point rays. No whole rays are stored. The points of intersection with given surfaces are stored in files corresponding to individual surfaces.
Nothing is written.
It runs programs 'srp', 'crt' and 'crtpts'. Input data for the complete ray tracing in spherical coordinates. Example for program crt.for in spherical coordinates. A sample synthetic model created during the technical session of the SW3D consortium meeting in June 1998. Comparison with the results of package CRT and and with the exact solution.
