Fig. 2From: Regularized magnetotelluric inversion based on a minimum support gradient stabilizing functional1D-layered model inversion results of a model A, b model B, c synthetic sounding curve of the model A, and d synthetic sounding curve of model B. x in horizontal axis is the logarithm of the depth, and the unit of depth is km. Thick gray line indicates a profile of the synthetic model, and thin lines with different colors correspond to different stabilizing functionals as shown in the legend on the topBack to article page
