Cross-section of the models. Cross-section of the models with a \(\hat{\alpha }^{S_1}=0.96\) using weighting function \(\varvec{w}^{S_1}\), and b \(\hat{\alpha }^{S_2}=0.90\) using \(\varvec{w}^{S_2}\). White squares indicate the location of the magnetized blocks of the true model. On the upper right of each panel, the value of \(\Delta\) is displayed
