BarbosaEuler deconvolution is a technique based anomaly measurements, its derivatives and structural index. The objective is to estimate the base level of the data, horizontal and vertical positions of the source, usually assuming a tentative structural index. Derivatives are calculated using different techniques and different methodologies exist to indicate the correct structural index. Most of the approaches define the correct depth estimates based on structural index estimated. We modeled anomalies magnetized by vertical and inclined directions, generated by an isolated magnetic monopole and calculated its analytical derivatives in order to show what expect from Euler deconvolution estimates for single sources. We then analyzed estimates over the source

influence area and at the borders. These examples clearly show an outstanding pattern for depth and base level estimates when the correct structural index is used. The estimates at these cases, and only at these cases, are constant over the anomaly position. For these cases, this pattern can clearly identify the correct structural index, related to the nature of the source.
