Posterior probability distributions of key molecular species and photospheric temperature retrieved with the canonical atmospheric model described in Section 3, shown in orange. Also shown in blue are the corresponding results with C₂H₆ removed from the model, whereby a peak in the DMS posterior is found. Horizontal points with errorbars denote the median and 1-σ interval of the distribution of the same colour, while arrows denote 2-σ upper limits.
