Assessment of inversion error for the 2D resistivity model before outlier removal: (a) Histogram displaying the distribution of absolute percentage errors between calculated and measured apparent resistivity values, indicating the overall data misfit; and (b) Scatter plot illustrating the correlation between measured and calculated apparent resistivity, with deviations from the ideal 1:1 line representing the misfit. The L1-norm and L2-norm data misfits are also provided.
