Fig. 11From: Invariant TE and TM magnetotelluric impedances: application to the BC87 datasetStatic-shift factors for the different sites for the cases of ρ− ↔ TM and ρ+ ↔ TM. Notice that factors are about two orders of magnitude larger in the former case than in the latter. The three signaled sites are the same depicted in detail in this figureBack to article page
