This is supplementary material to Schleich et al. (2024). The content of the provided data repository (also described in the file "content.txt") is as follows:

ADDITIONAL ANALYSIS

This folder contains a collection of ancillary data products for the evaluation of the retrievals performed in this work.

• 'bayes-factor' contains the data tables for evaluating the Bayes' factor for each separate collection of models(*)
• 'corner-plots' contains a collection of all corner plots associated with the individual input cases
• 'fit-residuals' contains all fit residuals for the individual atmospheric retrievals performed in this work (used to make Fig. C.1)
• 'resampled-pt-profiles' contains resampled p-T profiles to generate Figs. 6 and F.1
• 'retrieval-accuracy' contains additional plots related to the accuracy of each retrieval (used to make Fig. 5, as well as Figs. E.1 - E.5)

(*) SIDE NOTE:
Table headers in the "bayes-factor" data tables reference evidence reported from MultiNest (variable "Z"), and calculated Bayes factor (variable R). The case with log(R) = 0 is necessarily the reference case, and outliers are marked in a binary table with 1 (|log(R)| > 5) or 0 (|log(R)| < 5). In all cases, "log" refers to the natural logarithm.

• If someone actually reads this, I'm sorry. I also spent way too much time trying to track down if the values reported in MultiNest are natural or base-10 logarithm. I have now been convinced that it is worth it, always, to either specify "ln" for the base-e logarithm, or give the base of your logarithm if your write it down (i.e. log_10(X)) -Simon.

RETRIEVAL RESULTS

This folder contains the data products associated with the retrieval runs for each synthetic spectrum. The sub-directories are aranged by the following keys:

• 'drs' and 'pandexo' refere to the two noise cases considered
• 'inv-t' and 'norm-t' refere to the two underlying p-T profiles used to make the synthetic spectra
• 'hpc', 'mpc', and 'lpc' refere two the three cloud-top pressure cases considerd

Each individual folder contains (1) the TauREx parameter files for running retrievals using the selection of p-T profiles, (2) a folder called 'results', which containts the associated data products, and (3) a folder called 'chains', which stores the ancillary data products associated with the MultiNest sampling runs of each retrieval.

 We note that for the "drs_inv-t_mpc" case, the chains for the isothermal, 2-point, and 4-point runs have been lost

SYNTHETIC SPECTRA

This folder contains data products associated with the sample of synthetic transmission spectra.

• 'pt-profile_*.csv' are csv-files containing the p-T points used to make Figure 1 , and to generate the synthetic transmissions spectra
• 'forward-models' contains TauREx parameter files and forward models for the sample of synthetic transmission spectra. Each of the sub-directories also contains a faux-spectrum representing the wavelength-map of NIRSpec PRISM
  • 'no-clouds' contains contains the above for generating Figure 3.
  • 'inv-t' contains forward models using the "inverse" p-T profile
  • 'norm-t' contains forwrad models using the "monotonic" p-T profile
