Impact of the position of the phase discontinuity on the CoG measurement. Top: sensitivity to a phase discontinuity with respect to the position of the discontinuity in the subaperture (SA) for different fields of view (FoV). The simulation is carried out for a = 0.05 (weak-phase regime). Bottom: 1D illustration of the free parameter, the position of the discontinuity.
