Fig. 6

Data fit shown with apparent resistivity and phase curves. Characteristic data fit for the resistivity model. Data are points, both apparent resistivity (upper panels) and phase (lower panels), with corresponding error bars, and model responses are lines, dashed for the initial inversion run and solid for the additional run, where static shifts have been corrected. a A MT site with data points that had high phase tensor skews and were removed (shaded points near a period of 10 s). Note that, rather than removing data, the adjusted error bars effectively down-weight the non 2-D segments of the data (see text for details). b A MT site and c is an adjacent telluric-only site, a base and local pair
