JWST/NIRCam Transmission Spectroscopy of the Nearby Sub-Earth GJ 341b -- Supplementary Material

Supplementary material for 'JWST/NIRCam Transmission Spectroscopy of the Nearby Sub-Earth GJ 341b' by Kirk et al., AJ (2024). This repository contains six categories of data products: Data reduction reproduction — Eureka! control files (.ecf) and parameter files (.epf) alongside Tiberius input parameter files. These allow replication of our data reduction, light curve fitting, and transmission spectra extraction using the open-source code Eureka! and Tiberius. Stellar spectra — (Non flux calibrated) observed stellar spectra of GJ 341 for all three NIRCam visits as extracted with Eureka! and Tiberius. We also include flux calibrated stellar spectra for all three visits as extracted with Tiberius. Light curves — Reduced white and spectroscopic light curves from three data reduction codes (Eureka!, Tiberius, and Tswift) for all three NIRCam visits. Transmission spectra — Reduced transmission spectra from three data reduction codes (Eureka!, Tiberius, and Tswift) for all three NIRCam visits. Forward models — Set of four atmosphere forward models as presented in Kirk et al. 2024. Retrieved models — The median retrieved atmosphere model for each of the three reductions (Eureka!, Tiberius, and Tswift) as presented in Kirk et al. 2024.
