Absolute closure-phase differences (in degrees) between the star with a transiting planet (Fig. 8) and the star alone (Fig. 1) for all the instruments of Table 2. The black colour corresponds to the smallest prototype planet Kepler 11-f of Table 4, the red to the intermediate planet HD 149026 b, and the blue to the largest planet CoRoT 14-b. The star symbols connected with solid lines correspond to the planet phase entering the stellar disk (see Fig. 8), the circle symbols connected with dotted line to the planet at the centre of the stellar disk, and the triangles connected with dashed line to the planet exiting the stellar disk.
