Double Trouble (GJ 1132b JWST Transits NIRSpec G395H) — Supplementary Material
收藏资源简介：
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: 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! Transmission spectra — Reduced transmission spectra from three data reduction codes (Eureka!, FIREFLy, and ExoTiC-JEDI) for both G395H visits. Stellar spectra — Flux calibrated observed stellar spectra of GJ 1132 from each G395H visit. 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. For any additional data requests or questions, please contact: ryanjmac@umich.edu
本材料为May与MacDonald等人于2023年发表在《天体物理学杂志快报》（ApJL）的论文《双重异象：利用詹姆斯·韦布空间望远镜（JWST）近红外光谱仪（NIRSpec）G395H模式观测超级地球GJ 1132 b的两次凌星事件》的补充材料。本数据集仓库包含四类数据产物： 1. 数据还原复现 — 包含两次G395H观测的Eureka! 控制文件（.ecf）、参数文件（.epf）以及保存的第三阶段（Stage 3）输出结果。借助这些文件，用户可利用开源代码Eureka! 复现本文的数据还原、光变曲线拟合与透射光谱提取流程； 2. 透射光谱 — 包含两次G395H观测的、由三款数据还原代码（Eureka!、FIREFLy与ExoTiC-JEDI）生成的已校准透射光谱； 3. 恒星光谱 — 来自两次G395H观测的、经过流量校准的GJ 1132宿主恒星实测光谱； 4. 反演结果 — 包含两次G395H观测（基于Eureka! 数据还原流程）的大气与恒星污染反演结果所生成的角图（corner plot）以及参数统计摘要。本次反演使用了开源代码POSEIDON。 若有额外数据需求或疑问，请联系：ryanjmac@umich.edu
