a) Broadband on-sky PSF of a cMWS incorporating the HMWS of Fig. 8, showing 1 /λ radial dispersion of PSF copies. The location of the APP dark hole at λ = 633 nm is illustrated by the shaded region, spanning 2.7−6λ/D, although this is not directly visible in the stacked image data. b) Chromatic response of each mode, binned to Δλ = 20 nm wavelength intervals; colours correspond to the modes of Fig. 9. The 633 nm calibration wavelength is shown by the vertical dashed line, and the mean spectral transmission T(λ) is shown in the upper panel. Defocus Z₃ (green) shows indications of 1 /λ scaling, illustrated by the diagonal dashed line.
