A The residual anomaly for the data indicated as (a) in Fig. 3. B The residual anomaly predicted by the reconstructed model for region (a). C The weighted error of the map calculated from the subtraction of the predicted anomaly and the observed anomaly, weighted by the inverse covariance square root (\(W_{\textrm{d}}\)). D The graph shows the Gaussian histogram for the same weighted error
