Fig. 4From: A simple method to evaluate the uncertainty of magnetotelluric forward modeling for practical three-dimensional conductivity structure modelsMT sounding curves scaled by the square root of the period and the coefficient of variation of a rotational invariants and b impedance elements rotated to the \(\left( {x_{{\text{N}}} ,y_{{\text{E}}} } \right)\) coordinate system for site NM04 of the NW Pacific models. Colored lines are the sounding curves for the ten models. Symbol with error bar indicates the mean and the standard deviation of the ten samplesBack to article page
