GNGTS 2016 S essione 3.1 507 n . The technique used for estimating n is described in Fedi (2007), Florio and Fedi (2006), and Fedi et al. (2009) and consists of forming along any ridge the scaling function, τ k : (2) Then, we use the following equation to evaluate the structural index ( N ), which is strictly related to the source parameter. N=-n+k (3) where k is the order of differentiation of the magnetic field. So, the homogeneity degree was evaluated for most of the ridges and the depth values estimated are in good agreement with the depth of the singular points calculated by the geometric Fig. 3 – A) Comparison between the Multiridge depth results and the magnetic model of Mancinell et al.
