Numerical computations of the polarized flux Q in our Venus model in the Hα filter (λ0 = 656 nm) after the introduction of atmospheric seeing S (arcseconds). An atmospheric phase screen is applied to the fluxes in orthogonally polarized states, which are then recombined to obtain F and Q; the signed degree of linear polarization is computed as Ps = −Q/F (Equation (4)). The middle and right panels show the progressive blurring of the modeled ringlike pattern for S = 0﹩\mathop{.}\limits^{\unicode{x02033}}﹩5 and S = 1﹩\mathop{.}\limits^{\unicode{x02033}}﹩5, respectively.
