Spectral energy distributions at t = 2 × 10⁸ yr for (red) e_b = 0.0, (blue) e_b = 0.2, and (black) e_b = 0.4. The solid lines stand for the combined emission from star and disc; the dashed lines represent the disc alone. In the bottom panel, flux ratios relative to the disc with e_b = 0.0 are plotted. The fluxes are scaled marginally such that they converge at a wavelength of 1 mm.
