Double Trouble (GJ 1132b JWST Transits NIRSpec G395H) — Supplementary Material

<p>Supplementary&nbsp;material for '<i>Double Trouble: Two Transits of the Super-Earth GJ 1132 b Observed with JWST NIRSpec G395H</i>'&nbsp;by&nbsp;May &amp; MacDonald et al., ApJL&nbsp;(2023).</p><p>This repository contains four categories of data products:</p><ol><li><strong>Data reduction reproduction</strong> — Eureka! control files (.ecf) and parameter files (.epf) alongside saved Stage 3 output for both G395H visits. These allow replication of our data reduction, light curve fitting, and transmission spectra extraction using the <a href="https://github.com/kevin218/Eureka">open-source code Eureka</a>!</li><li><strong>Transmission spectra</strong> — Reduced transmission spectra from three data reduction codes (Eureka!, FIREFLy, and ExoTiC-JEDI) for both G395H visits.</li><li><strong>Stellar spectra </strong>— Flux calibrated observed stellar spectra of GJ 1132 from each G395H visit.</li><li><strong>Retrievals</strong> — Corner plots and parameter statistics summaries from atmospheric and stellar contamination retrievals applied to both G395H visits (Eureka! reduction). The retrievals used the <a href="https://github.com/MartianColonist/POSEIDON">open-source code POSEIDON</a>.</li></ol><p>For any additional data requests or questions, please contact: ryanjmac@umich.edu</p>
