Fig. 16From: 3-D inversion of magnetic data based on the L1–L2 norm regularizationPlot of \(\Delta\) for \(\alpha\). Plot of \(\Delta\) for \(\alpha\) in the range of 0.60 to 0.99 with an interval of 0.01, using the weighting function of a \(\varvec{w}^{S_1}\), and b \(\varvec{w}^{S_2}\). The solid triangles, circles, squares, and diamonds indicate the case of \(\sigma _0 = 0.5, 1.0, 5.0\), and 10.0 nT, respectivelyBack to article page
