Variation in total stray-light estimated for a test sky pointing (, , with a position angle of ϕ = 25°, with an increasing high-resolution radius R_min (see Sect. 2.2) for the numerical nonaxisymmetric and envelope axisymmetric NDI models. Top panel: Absolute flux of the estimated stray-light per pixel, in e⁻ px⁻¹. Bottom panel: Absolute variation in estimated stray-light flux with increasing high-resolution radius. The stray-light flux estimate converges to a semi-constant level for increasing R_min.
