Fig. 1From: Linking strike directions to invariant TE and TM impedances of the magnetotelluric impedance tensorThe continuous and dashed lines correspond to synthetic data for site 15 of the COPROD2S1 dataset proposed by Varentsov (1998). The data are provided as apparent resistivities and phases for 12 periods. The colored dots represent the distorted values assuming twist = 20°, shear = 30° and strike = 30°. A small random error of 0.1% of the \(xy\) and \(yx\) impedances was added to the distorted dataBack to article page
