Products and Models for "Escaping Helium and a Highly Muted Spectrum Suggest a Metal-Enriched Atmosphere on Sub-Neptune GJ3090b from JWST Transit Spectroscopy"

This repository includes the data for Ahrer et al. 2025: Escaping Helium and a Highly Muted Spectrum Suggest a Metal-Enriched Atmosphere on Sub-Neptune GJ3090b from JWST Transit Spectroscopy All retrievals include the posterior sample, the best-fit model, the median model and at least the 1-sigma range (some include 2-sigma too). The folder structure is as followed: Combined white light curve fit The inputs and outputs for the combined white-light fit of all 4 transits. Grid retrievals (NIRSpec only) The outputs of the grid retrieval from ScCHIMERA, both in equilibrium and disequilibrium Helium analysis the necessary data products to reproduce the analysis of the He feature (pixel-level spectra and light curves) NIRISS SOSS flux calibrated spectra Retrievals Outputs from the retrieval codes, divided into Aurora, POSEIDON and SCARLET Stellar spectra Extracted time-series stellar spectra for both instruments, both reductions and all visits Transmission spectra Transmission spectra for NIRSpec and NIRISS for both reductions as presented in the paper
