Summary: The Central Andes gravity data (6,151 records)
were compiled by Professor Gotze and the MIGRA Group. This data base was
received in April, 1997. Principal gravity parameters include Free-air
Anomalies and Bouguer Anomalies (terrain and mass corrected). The gravity
station data have been adjusted to the International Gravity Standardization
Net 1971 (IGSN 71). The gravity anomaly computation uses the Geodetic
Reference System 1967 (GRS 67) theoretical gravity formula. The data are
randomly distributed within the area bounded by 64 - 71 degrees West and 20 -
29 degrees South in the Central Andes of South America.
