S-FFT Refinement

An alternative way of refining phases with the origin-free modulus sum function S is shown that, instead of applying the tangent formula in sequential mode, applies it in parallel mode with the help of the fast Fourier transform (FFT) algorithm. The main control parameters of this procedure are:
