Comparison of the species and cloud posterior distributions for the cloud-free and cloudy (gray cloud deck; R. J. MacDonald & N. Madhusudhan 2017) retrieval models for LTT 9779 b’s dayside emission (orbital phase of 180°). The full atmosphere, cloud-free model is shown in purple, while the cloudy model is shown in green. No degeneracies between the H₂O, CO, or CO₂ abundances and cloud pressure are observed. Furthermore, H₂O abundances are comparable between both cloud-free and cloudy models. This indicates the inclusion of a gray cloud deck does not mimic or obscure the molecular absorption signatures in the dayside emission spectrum, and that the detections of H₂O, CO, and CO₂ are robust to the assumption of clouds.
