Radial profiles along the wind direction (top panel) and asymmetry factor as defined in Eq. (12) (bottom panel) for the simulated data sets. The solid black line uses the nominal parameters from Table 1 (image shown in the bottom right of Fig. 3). Other lines differ in one parameter playing a role in the asymmetry: shorter wavelength (H-band, λ = 1.6 μm, blue line), lower altitude (z = 8 km, green line), lower wind speed (vwind = 20 m s−1, red line), and slower AO loop frequency (fAO = 800 Hz, yellow line). The DM cutoff frequency is at 20λ/D (dotted grey line). In the bottom plot, solid lines indicate the asymmetry from the simulated images and dashed lines show the prediction from Eq. (14).
