OG |
Observed gravity, in mGal |
FAA |
Free-air anomaly, in mGal |
SBA |
Simple Bouguer anomaly, in mGal |
ITC |
Inner terrain correction for a density of 2.67 g/cc, in mGal. See Code column for radius of correction. |
TTC |
Total terrain correction from the station to 166.7 km for a density of 2.67 g/cc, in mGal. |
Code |
Letter denoting the zone (radius) of the correction |
CBA |
Complete Bouguer anomaly reduced for a density of 2.67 g/cc, in mGal. |
ISO |
Isostatic residual anomaly,in mGal,assuming an Airy model for isostatic compensation of topographic loads. This model assumes a crustal thickness of 25 km, a topographic load density of 2.67 g/cc, and a density contrast across the base of the model crust of 0.4 g/cc. Isostatic correction would be difference between CBA and ISO values. |
