Example closed-loop performance for a 6-mode Zernike (left column) and Fourier (right column) mode cMWS for g = 0.8. a) N_i = 0 aberrated PSFs, with a_k = 1.0 radians rms per mode. b) Diffraction-limited PSF after N_i closed-loop iterations required to achieve convergence. PSF copies corresponding to each mode bias are labelled Z_{n ±} for Zernike modes and F_{nS/C ±} for Fourier modes, where the index S/C denote the sine and cosine mode phases respectively, and mode number corresponds to the circled regions of influence in the APP dark hole. The white circles overlaid on the Z₄ ± modes indicated the r = 1.22λ/D region of interest used for wavefront measurement. Note also the differing angular extent of each APP, which cover 180° and 90° for the Zernike/Fourier designs respectively. c) Azimuthally-averaged residual intensity plots corresponding to the PSFs of panels a) (green) and b) (blue); shaded regions denote 1σ variance averaged over the APP dark hole. d) Science PSF Strehl ratio (black diamonds) and residual rms wavefront error (red squares) as a function of iteration number N_i. Vertical dashed lines indicate the point of convergence.
