Normalized synthetic images in scattered light, at steady state, for a wide disc of parent bodies initially extending to a_crit, and for different orbital configuration of the binary, where the value a_crit is kept constant and e_b varies. The upper left panel is a test case with no companion and the next 5 runs are for e_b = 0, 0.1, 0.3, 0.5 and 0.75 respectively. The location of the a_crit radius is shown by the dashed black circle. The binary configuration is schematized in the small white square at upper right of each panel, where the region within a_crit is shown as a filled black circle. All distances have been normalized so that a_crit = 1.
