CUB20_J362D28_raytracer.tar.gz includes the following subdirectories:

manual	    directory with a manual for the software.

src         directory with source codes for D2tracerdn, conv_model,
	    f_lay, iasp_tbl and pr_sssc programs.

bin         Binary executable files and shell-scripts.

model       directory holding a 3D model file CUB20_J362D28_raytracer.f.asc.

PLOTTING-SCRIPTS   directory holding shell-scripts used to plot
		   maps and ray diagrams, based on GMT package.

EIL_test    directory with files illustrating a practical
	    example of using this software (see manual)

NOTE:

Current distribution of the raytracer software has been assembled to work with SUN Solaris 7 operating system. Portability of binary executable files also depends on configuration of FORTRAN libraries. With some configurations, distributed binary files may not run properly and should be recompiled from sources. GMT version 3.3.3 has been used in plotting scripts.
