Eigenray --- Eigenray Acoustic Ray Tracing Code
(B. Dushaw, Applied Physics Laboratory, U. Washington)
Describes a Fortran ray model which follows closely the Bowlin ray code "Ray" (written in C) and drawing on earlier work with John Colosi. This version is optimized for long-range, deep-water calculations.

(R.M. Jones, J.P. Riley, T.M. Georges, National Oceanic and Atmospheric Administration)

 Ray (v.1.47) (J. Bowlin/Woods Hole Oceanographic Institution)
This code is apparently used by quite a few people but nobody is actively developing it further.
The master copy is from Arthur Newhall/WHOI.
