Fig. 2From: Reframing the magnetotelluric phase tensor for monitoring applications: improved accuracy and precision in strike determinationsa Diagonal elements of the phase tensor derived from the impedance tensor shown in Fig. 1. The color code is \({\Phi }_{11}\) green and \({\Phi }_{22}\) yellow. The black continuous line corresponds to error-free values. b The corresponding off-diagonal elements. The color code is \({\Phi }_{12}\) green and \({\Phi }_{21}\) yellow. The black dashed line corresponds to error-free valuesBack to article page
