The level contours represent the misfit to the data. a Strike of 30º and \({\rho }_{+ }\,{\mathrm{as}}\,{ \rho }_{xy}\) with a large misfit. b Strike of 30º and \({\rho }_{+ }\,{\mathrm{as}}\,{ \rho }_{yx}\) with a small misfit. The minimum corresponds to the true values of shear and twist. c and d are the corresponding versions for a − 60º strike (see text for details)
