Disc-integrated SED for the nominal case as well as for two companion-free cases: one where the PB ring is at the same distance, i.e. 85 au for the centre of the ring, as in the nominal case, and one where the disc is moved outward by 75%. We also plot, as a comparison, a blackbody profile at a distance of 85 au from the central star.The different SEDs have all been normalised to their maximum value.
