Top: PWFS slopes vector for a flat wavefront, a 300 nm RMS tilt, and the same tilt added to a 120 nm RMS fitting error wavefront ϕRes, showing the attenuation of the signal. Data are smoothed by a window of 50 samples in width for clarity. Bottom: recorded PWFS response curve to three modes – tilt and Karhunen–Loève 20 and 3000 – with and without the same ϕRes. The tilt curve without residuals saturates around 750 nm RMS. The AO setup simulated is described in Sect. 3.
