OOMAO PSF fitting with our model. Left: circular average for PSFs (given in photons). The vertical grey line corresponds to the AO cutoff radius. Right: corresponding circular average for OTFs (normalized to unity at the null frequency). From top to bottom, three wavelengths are scanned from 500 nm to 1220 nm. Colours correspond to three values of the OOMAO required r₀. Solid curves: OOMAO. Dashed: fitting. Dotted: residuals. All PSFs, for all wavelengths, are sampled at Shannon–Nyquist.
