Fig. 6From: Invariant TE and TM magnetotelluric impedances: application to the BC87 datasetFit to the data for the invariant ρ− assumed as the TM mode. 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, just as they don’t for the strike of − 30° in Fig. 5. 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
