We have presented a new method for selecting the best source location estimates in 3D Euler deconvolution. Our approach has drastically reduced the number of the selected 3D Euler solutions to only one per anomaly. This is possible because our method does not select Euler solutions based on their statistical consistency after a cluster analysis. Rather, in our method this selection is grounded on the theoretical analysis of the estimators for the horizontal and vertical source positions in 3D Euler deconvolution as a function of the x- and y-coordinates of the observations. Our approach consists in detecting automatically the regions of the anomaly producing consistent estimates of the source horizontal coordinates.
