CT Cha b

This repository contains the codes used to extract the emission spectrum of the circumplanetary disk surrounding the planetary mass companion CT Cha b and the results associated with this work To use the code, just run the Extract_b notebook. The code for the final subtraction of low-frequency modulations is not made public, as it is proprietary work. Interested people should request access to Milou Temmink. The files CTChaA_3ABC4ABC_final.txt and CTChab_3ABC_final.txt contain the final extracted spectra for A and b. The files CTChaA_data_model.txt and CTChab_data_models.txt contain the extracted spectra, the best-fit model and the contributions of each of the individual molecules. The file Data_pipelined.zip contains the 3D cubes of the files at stage 3 of the jwst pipeline.本仓库包含用于提取环绕行星质量伴星CT Cha b的周行星盘（circumplanetary disk）发射光谱，以及本研究相关配套成果的代码。 使用该代码仅需运行Extract_b笔记本文件。由于低频调制最终扣除代码属于专有工作，暂未对外公开，有需求者可向Milou Temmink申请访问权限。 文件CTChaA_3ABC4ABC_final.txt与CTChab_3ABC_final.txt分别存储了针对恒星CT Cha A与伴星CT Cha b的最终提取光谱。 文件CTChaA_data_model.txt与CTChab_data_models.txt则包含了提取得到的光谱、最佳拟合模型，以及各单个分子的贡献组分。 文件Data_pipelined.zip存储了经JWST流水线（jwst pipeline）第三阶段处理的对应文件的三维数据立方体。
