Emitted light spectral energy distribution λL_p,em,λ (Eq. (37)) of our HD 189733b simulation as a function of wavelength at several viewing angles α (α = 0° is the sub-stellar point). Spectral features remain qualitatively similar at different viewing angles with a ~1 order of magnitude difference between the sub-stellar point (α = 0°) and anti-stellar point (α = −180°). The peak wavelength is found to be at ~2 μm.
