DESCRIPTION

The pgc_pickfile handler is intended to be launched by the mail_parser(1) utility. The pgc_pickfile handler takes email from the Geological Survey of Canada at the Pacific Geoscience Center, interpreting their "Loon Pickfile" format and placing the results into a CSS database. The database is specified in the mail_parser.pf parameter file. Three additional tables in the mail_parser.pf parameter file translate the channel names, location programs, and Canadian velocity models into equivalent text strings to go in the CSS database. Note that the error ellipsoid description for LocEq generated errors is an approximation to the true error ellipsoid for this solution. It is based on the lat, lon, depth errors calculated at the earth's surface from LocEq; these errors are represented in the ellipsoid such that smajax and sminax always lie parallel to the earth's surface. Strike direction is consistent with Aki & Richards, section 4.5. All definitions conform with css3.0 schema definitions for error ellipsoid.

BUGS AND CAVEATS

Sometimes a re-analysis of the same event is sent out via email. the pgc_pickfile handler does not account for receiving updated copies of the same earthquake.
