Fig. 10From: A simple method to evaluate the uncertainty of magnetotelluric forward modeling for practical three-dimensional conductivity structure modelsDistribution and RMS of the residuals for the S Atlantic model. a Histograms of residuals normalized by the standard errors of the observed MT responses \(\varepsilon^{{{\text{obs}}}}\) (top) and by \(\sqrt {\left( {\varepsilon^{{{\text{obs}}}} } \right)^{2} + \left( {\varepsilon^{{{\text{syn}}}} } \right)^{2} }\) (bottom). Blue dashed lines indicate \(\pm {\text{RMS}}_{1}\) and \(\pm {\text{RMS}}_{2}\), red solid lines indicate the normal distributions that the mean is zero and the standard deviation is \({\text{RMS}}_{1}\) and \({\text{RMS}}_{2}\), respectively. b Sitewise \({\text{RMS}}_{1}\) (gray) and \({\text{RMS}}_{2}\) (red)Back to article page
