Theoretical spectra after continuum subtraction of molecules that we have searched for in the cross-correlation analysis. A similar figure for H₂O, CO, CH₄ and SiO is shown in the main text, Fig. 6. From top to bottom, the additional molecules shown here are CO₂ in cyan, NH₃ in magenta, HCN in light blue, C₂H₂ in dark red, H₂S in pink, O₃ in purple, and PH₃ in orange. Grey areas correspond to the wavelength windows covered by our observations.
