|The gravity station data total 28493 records. This data base was received in April
1997. Principal gravity parameters include Free-air Anomalies which have been adjusted
to the International Gravity Standardization Net 1971 (IGSN 71), and the gravity anomaly
computation uses the Geodetic Reference System 1980 (GRS80) theoretical gravity formula
(Somigliana formula). The data are randomly distributed within the boundaries of Spain.
