Fig. 10From: Invariant TE and TM magnetotelluric impedances: application to the BC87 datasetThe effect of leaving the TE apparent resistivity curves out of the inversion process is that the computed TE curves of the roughest models are approximately parallel to the field curves. It can be observed that the shifts for the three sites shown are far larger when assuming that ρ− is the TM resistivity than when assuming that ρ+ is the TM resistivityBack to article page
