Laboratory-measured Strehl (top) and residual tilt (bottom) performance of NAOMI vs. WFS incident flux, at 80% seeing conditions, i.e. λ/r₀ = 1.1″ and τ₀ = 2.5 ms at λ = 500 nm. The former performance level of STRAP is also indicated. The coloured lines correspond to the performance measurements for each loop frequency (f), EM gain (g), loop gain (K_I), and controlled mode (modes) settings. The coloured areas are the optimal settings for a given flux range. The WFS incident flux is converted into an R magnitude assuming a transmission to the WFS of 10%. The specifications for the Strehl and residual tilt vs. R magnitude are shown as black dots. The transitions between modes at 500 Hz were chosen based on saturation limits. The transition between modes at lower frequencies were chosen at a flux level two times higher than the Strehl performance intersections, to help with the stability of the AO loop close these transitions.
