Model 1: noise-free data (after Jagannadha Rao et al. [ 1993 ]). Inversion results obtained by the method developed here (in which the inverse parameters are formulated in the mixed logarithmed and non-logarithmed space; log(h), log(k), log(a), and θ) from “Initial guess 1” that is shown in the figure. “SD” and “GN” stand for the steepest descent and Gauss-Newton methods. See the text for details. The observed and predicted SP data are coincident with each other.
