Fig. 10

Separation of the discontinuous diffusivity function using SVD. Top left panel shows the analytic diffusivity function \(k_2\). Top right panel show the relative weight of the initial 45 terms of the separated function; the relative weight is computed as the sum of the amplitude of all previous terms, divided by largest amplitude. Lower panels show the functions F and G corresponding to the initial four terms
