COSI Data Challenges

The COSI data challenges are released on a yearly basis in preparation for the launch of the COSI Small Explorer (SMEX) class mission in 2027. The data challenges are based on simulated data, which is intended to closely mimic the real flight data. Every year they have increasingly more realistic source and background models, and they are analyzed with increasingly complete and matured analysis tools. The two main goals of the data challenges are to facilitate development of the COSI data pipeline and analysis tools and provide resources to the astrophysics community to become familiar with COSI data.COSI数据挑战赛（COSI data challenges）每年发布一次，旨在为2027年发射的COSI小型探索者（Small Explorer, SMEX）级任务做好筹备工作。该挑战赛基于模拟数据构建，旨在高度复刻真实飞行数据。每年，挑战赛所采用的模拟数据会搭载愈发逼真的天体源模型与背景模型，相关分析工作也依托愈发完善成熟的分析工具开展。该挑战赛的两大核心目标：一是推动COSI数据流水线与分析工具的开发，二是为天体物理学界提供相关资源，帮助科研人员熟悉COSI相关数据。
