Notes. The upper part gives results for the PSF_AO convolved model and the lower part the Σ₂ values after zp-correction based on different regions Σ_zp for the models shown in Fig. 20. All values are normalized relative to the intrinsic azimuthal polarization $Σ Q_{ϕ}^{'}$ $\Sigma Q_\phi ^\prime$ .
