Program TRABOX is an initial value and boundary value (i.e. two-point)
seismic ray tracing program in Cartesian co-ordinates. It was initially
written by Malcolm Sambridge in 1987 at the Research School of Earth
Sciences, Australian National
University. The most recent modification was in
May 2001. It has
been tested under three different compilers, each giving the same
results on the 5 test problems. These are sun f77, GNU g77 and
Compaq-Alpha f77. Full details
of TRABOX can be found in the trabox
