Relative contribution to the radiation emitted at a given orbital phase from spherical shells around the system’s centre of mass (with a thickness of 0.05 AU) at two different energies. For clarity, we only present the results for a system inclination of i = 60°; the resulting maps qualitatively agree with those for an inclination i = 30°. We terminate the analysis at r = 1.5 AU, where the farthest edge of the computational volume is reached. Relevant orbital phases are annotated (see also Fig. 1).
