Summary: The gravity station data (59,933 records) were compiled by
various organizations.  This data base was received in June, 1993.
Principal gravity parameters include Free-air Anomalies and Simple
Bouguer Anomalies (no terrain correction applied). The following
assumptions have been made: the observed gravity values are
referenced to the International Gravity Standardization Net 1971
(IGSN 71); the gravity anomaly computation uses the Geodetic
Reference System 1967 (GRS 67) theoretical gravity formula.
