Magnetotelluric data (dots) and model response (solid lines). They are shown as apparent resistivity (Ap. Res.; ρ) and phase (φ) from all impedance components (off-diagonal, xy and yx, left column; diagonal, xx and yy, right column) at six selected (representative) sites. The locations of the measurement sites are indicated in Fig. 1 (site names: 2310; 2360; 4295; 4343; 6310; 6350). Assigned error floors are shown as error bars (see text for details). In general, the models fit the data
