Measurements (dots) and models (lines) for the wavefront transfer function for the three loop frequency and gain settings adopted for the NAOMI system. The settings are defined by the loop frequency (f), the HS speed, the crop (crop = 1) or region of interest (crop = 0) mode, and the integrator gain (K_I). The total delay (T) and the −3 dB bandwidth (BW) of the models are also given. Measurements and models are in agreement, confirming that the delays and scaling of the control loop are properly accounted for. See Sect. 3.1 for details.
