Absolute differences between the closure phases computed for the 2000 random baseline triangles in the case of a system without the presence of a hot Jupiter companion (CPh_noplanet) and a system star-planet (CPh_planet, see text and Fig. 11). The horizontal solid lines indicate the 1.0 and 0.3 degrees and the vertical dashed line the spatial frequency corresponding to the end of the third visibility lobe. The black, blue, green, and red colors denote the planet-star distance of [0.1, 0.25, 0.5, 1.0] AU, respectively. The maximum linear extension, the apparent radius, and the parallax are the same as Fig. 10.
