Kp−Δvsys contours for the free retrieval maximum-likelihood model (black) as well as CO-only (filled dark red), H2O-only (filled blue), and OH-only (filled cyan) models. Each model was generated using the retrieved maximum-likelihood parameters, setting the abundance of the included species to 10−3 and the abundances of all other species to 10−15. The contours are drawn at SNR = 2, 4, and 6. The contours enable us to asses both which species are present and whether there are velocity offsets between different species.
