Description

Data products from "Additional JWST/NIRSpec Transits of the Rocky M Dwarf Exoplanet GJ 1132 b Reveal a Featureless Spectrum" by Bennett et al. (2025). 

This repository contains the following: 

  1. Transmission Spectra: Reduced transmission spectra for all four observations as shown in Figures 3 and 4. Individual transit observations are included for each reduction pipeline (FIREFLy, Eureka!, and ExoTiC-JEDI) as well as weighted mean of all four visits, and the weighted mean of visits 2-4 (with Visit 1 excluded).
  2. Stellar Spectra: Flux-calibrated stellar spectra for each individual observation, along with the respective best-fit PHOENIX model (as seen in Figure 5). 
  3. Atmospheric Forward Models: All forward models used in Figure 6. 
  4. Retrieval Results: Corners plots and results files for POSEIDON retrievals run for all reduction pipelines. Includes results using the weighted mean for all four visits as well as results using the weighted mean of visits 2-4 (with Visit 1 excluded).

For any additional questions or requests, please contact Katie Bennett at kbenne50@jhu.edu.
