(a) Volume distributions DV(R) obtained by the different smoothing options in the EM iteration scheme. (b) Volume distributions DV(R) obtained by Tikhonov regularization. (c) Simulated experimental SAS data with noise and corresponding model scattering function. (d) The corner of the L-curve determines the optimum weighting factor for the cost function, which was chosen to be the entropy of the solution vector (blue) or the sum of its first (red) or second derivative (green), over the [{\cal G}]-test for the goodness of fit, which progresses from right to left with each iteration.
