Fig. 3From: Electrical signatures of the Earth’s crust in central India as inferred from magnetotelluric study(a) Dimensionality parameters (Swift’s and Bahr’s skew) are plotted for the present data set. Dots in a grey color indicate the Swift skew whereas dots in black indicate the Bahr’s skew. (b) The rms error in percentage is plotted against model roughness to obtain the trade-off parameter (Hansen, 1998). Optimal trade-off parameter is chosen.Back to article page
