I'm an astronomy graduate student working on a project analyzing transmission spectroscopy data from JWST to characterize exoplanet atmospheres. I'm currently trying to model the potential atmospheric composition of a warm Neptune, but I'm getting stuck disentangling the spectral signatures of methane, water vapor, and possible clouds or hazes that could be muting the absorption features. What are the current best practices or software tools for atmospheric retrieval in this context, and how do you approach degeneracies between chemical abundance and cloud parameters in your models?
