Eigenray --- Eigenray Acoustic Ray Tracing Code (updated August 2015)
(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.
