ADEPT: a program to estimate depth to magnetic basement from sampled magnetic profiles
Jeffrey D. Phillips
1978, Open-File Report 79-367
A fortran program computes depth to magnetic basement from the spatially varying autocorrelation function of a sampled magnetic profile. The depth calculation assumes a particular form for the autocorrelation function, and this assumption is tested against the measured autocorrelation function in order to reject invalid depth estimates....
