Point Mass Models and the Anomalous Gravitational Field.

摘要

Single- and multi-layer continuous and discrete anomalous mass distributions and its relation to the spectrum of the anomalous gravitational field are investigated. A fast procedure for the calculation of gravity anomaly degree variances from regularly distributed point masses is outlined. Emphasis is put on the central role of Fast Fourier Transform methods on the sphere for all numerical determinations of point mass models from harmonic coefficients and/or surface gravity anomaly data.
