1D models inverted from the average a det and b ssq impedances from the distorted 3D datasets (Fig. 12). The theoretical models of the mean 1D profiles, \(\sigma _{\text {R}}(z)\), from this setting with both linear (Eq. 3) and logarithmic (Eq. 4) scaling (black dashed lines) and the 1D model from the undistorted data (black solid line) are shown for comparison
