Bayes factor and confidence levels values for each retrieved spectroscopically active species in the “simplified noise” retrieval set. The heatmap is color-coded according to the Bayes factor values log₁₀(𝒦) and the confidence levels (in “sigma” values) are labeled within each cell whenever log₁₀(𝒦) is positive. The Bayes factor values were obtained by performing a retrieval including and excluding the molecule of interest and then using Eq. (1). These were then converted into σ through Table 2. The Bayes factor values can be found in Table D.7.
