Summary: The gravity station data (195 records) were compiled by 
Barbara Eckstein.  This data base was received in January 1987.  
Principal gravity parameters include Free-Air Anomalies and 
Simple Bouguer Anomalies (no terrain correction applied).  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.  The data are randomly distributed
within the Rhinelander area of northern Wisconsin.
