Figure 9: Results of a dipole-dipole survey carried out on the plane of Himera to detect buried archeological structures. (a) Map of the archaeological excavation (the black arrow indicates the position of the survey). (b) Filtered Jacobian damped LSQR imaging. (c) Standard least-squares constrain inversion. The black numbers indicate some resistive localized anomalies, which are well related to wall-like relics (red numbers).
