From: The Mag.num core field model as a parent for IGRF-13, and the recent evolution of the South Atlantic Anomaly

Fig. 8

The locations of SAA main minimum (top left), saddle point (top right) and second minimum (bottom left) for all IGRF candidate models are shown as an indication of the robustness of the results from our Mag.num model (blue cross). Minima and saddle point have been determined from a 0.05\(^\circ \) grid and in some cases the same value is found on two or more grid points
