Simulated illumination map at λ = 2.16   μm on Earth from a point source (up-left)- and from a K0V star (r_s = 0.85   R_⊙, M_V = 5.9) at z₁ = 8 kpc (right). The refracting cloud is assumed to be at z₀ = 160 pc with a turbulence parameter R_diff(2.16   μm) = 150 km. The circle shows the projection of the stellar disk (with radius R_S = r_s × z₀/z₁). The bottom maps are illuminations in the K_s wide band (λ_central = 2.162   μm, Δλ = 0.275   μm).
