Fig. 4From: Invariant TE and TM magnetotelluric impedances: application to the BC87 datasetFit to the data for a strike direction of − 30° or N30°W. The upper images are the data pseudo-sections and the ones below are the corresponding responses of the model. Notice that the pseudo-sections of the TE apparent resistivity don’t look alike at all in this case. The other three pairs indicate a good fit to the data. The TE apparent resistivity was not part of the inversion processBack to article page
