Evolution of the contrast with the phasing errors (blue) with the CSP1 design, (red) with the RAP1 design, (black) with the CSP2 design, and (green) with the RAP2 design. 1000 different error amplitudes are considered between 1 mrad RMS and 1 rad RMS. For each of them, 100 phasing errors are simulated and propagated, 100 PSFs normalized by their aberrated direct image peak are computed, and the average of the 100 resulting dark hole contrasts is plotted.
