Short note: The determination of inflection points on magnetic intensity profiles

Abstract

The inflection points on a total magnetic intensity profile are employed in many analytic interpretation techniques e.g. Grant and Martin (1966), Bean (1965), Moo (1965). The positions of points of inflection on the flanks of a magnetic anomaly are usually difficult to locate by inspection with reasonable accuracy. A simple analytic, trial and error, technique employing "moving strip'' central difference coefficients may be used to locate inflection points rapidly from the measured and/or smoothed magnetic intensity data points.
