Result of wavefront control with IFU error only (top), PIAA errors only (middle), and the full PIAAN (bottom). Red, blue, and green curves correspond respectively to the start point (DM flat), the result after WFE optimization, and the result after contrast optimization. The filled area corresponds to the envelope covered by the six fibers and the solid line to their average. The resulting DM shaped applied after each step is shown on the right of the plots. M is calibrated at 730 nm.
