Fig. 9From: 3-D inversion of magnetic data based on the L1–L2 norm regularizationCross-section through the \(x=0\) km profile. Cross-section through the \(x=0\,\hbox {km}\) profile of the models derived by L1–L2 norm combined regularization using weighting function \(w^{S_2}\) with a \(\alpha = 0.0\), and b \(\alpha = 1.0\).and c \(\alpha = 0.8\). White squares indicate the location of the magnetized blocks of the true modelBack to article page
