  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
<http://folkworm.ceri.memphis.edu/ew-doc/PROGRAMMER/GlobalMessages.html>
messages.

Rayloc_ew reformats the input and calls FORTRAN RayLoc processing
machinery. The output of rayloc_ew
is TYPE_RAYLOC
<http://www.isti.com/%7Eilya/Message_Format_TYPE_RAYLOC.html> 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.
