Closed-loop performance of the linear and nonlinear reconstructor for different atmospheric conditions. The solid line shows the mean Strehl at 875 nm over the five experiments, while the filled region indicates the minimum and maximum Strehl over the experiments. The top row shows the performance for a wind speed corresponding to median conditions at LCO with a -weighted value of 18 m s⁻¹, while the bottom row uses double that value. The different columns correspond to different values for the seeing of the simulated turbulence. Videos of the closed-loop tests are available at online.
