Efficient Truncation Criterion for the Parameter Estimation of a Stratified Ground Block

A truncation criterion to solve the vector potential integrals proposed by Takahashi and Kawase is described in this letter. The main aim of those integrals is to estimate the depth and resistivity parameters of a stratified ground block. The derivation of the proposed criterion considers the error introduced by the infinite limit truncation of the integrals. In addition, an efficient solution can be obtained by the use of the trapezoidal rule of integration.
