# Earthworm Modules:
RayLoc_ew Overview

(last revised 13 July, 2004)
Rayloc_ew is an Earthworm Module to perform global relocation of earthquakes and travel time computation.
Rayloc_ew is an Earthworm-style wrapper around a Fortran program RayLoc written by Ray Bulland.
Rayloc_ew attaches itself to the input ring and monitors the ring buffer for the TYPE_LOC_GLOBAL messages.
Rayloc_ew reformats the input and calls FORTRAN RayLoc processing machinery. The output of rayloc_ew
is TYPE_RAYLOC message, which is written to the output ring.
The rayloc_ew program is compiled and tested out on a Solaris platform (with gcc and g77 compilers).
The wrapper module is written that conforms to the Earthworm standards (logging, heartbeat, proper termination etc).
The wrapper accepts TYPE_LOC_GLOBAL messages and outputs TYPE_RAYLOC as described above.
Rayloc_ew requires three model files (tau.table, ak135.hed, ak135.tbl). These files are parts of rayloc_ew distribution.
