Description

Supplementary material for 'Double Trouble: Two Transits of the Super-Earth GJ 1132 b Observed with JWST NIRSpec G395H' by May & MacDonald et al., ApJL (2023).

This repository contains four categories of data products:

  1. Data reduction reproduction — 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 open-source code Eureka!
  2. Transmission spectra — Reduced transmission spectra from three data reduction codes (Eureka!, FIREFLy, and ExoTiC-JEDI) for both G395H visits.
  3. Stellar spectra — Flux calibrated observed stellar spectra of GJ 1132 from each G395H visit.
  4. Retrievals — Corner plots and parameter statistics summaries from atmospheric and stellar contamination retrievals applied to both G395H visits (Eureka! reduction). The retrievals used the open-source code POSEIDON.
