Spatial profiles considered in the models, peaking at unity: star and planet separated by 40 pixels (solid and dashed black lines). The rest correspond to a sphere or a face-on disk with a radius of 25 pixels and whose profiles are homogeneous (green), Gaussian (red), inverse Gaussian (blue), and ring-like (violet). The star–planet separation and the sphere/disk radius are arbitrarily large compared to the ones modeled (see text), and have been selected for clarity.
