摘要
CHEOPS 是一台专门设计用于监测围绕明亮恒星运行的凌日系外行星的空间望远镜。2023 年 9 月，CHEOPS 完成了其名义任务，并仍处于极佳的运行状态。该任务已延长至 2026 年底。在整个在轨调试和名义运行期间收集了科学和仪器数据，从而能够对任务性能进行全面分析。在本文中，我们展示了这项分析的结果，目标有二：首先，我们旨在向科学界通报任务的现状以及随着仪器老化可以期望的表现。其次，我们希望本出版物能作为未来任务的遗产文档，提供来自 CHEOPS 成功运行的见解和经验教训。为了评估仪器的在轨性能，我们制定了一项全面的监测与表征计划。该计划由专门的观测组成，使我们能够表征仪器的响应。除了标准收集的名义科学和遥测数据外，这些观测还为检测、建模和校正仪器系统误差，发现和处理异常，以及比较仪器实际性能与预期提供了输入。CHEOPS 测量的精度已使任务目标得以实现并超越。对仪器系统误差的仔细建模使得在光变曲线分析阶段能够显著提高数据质量，从而获得更精确的科学测量结果。CHEOPS 符合任务的核心科学要求。尽管老化现象可见，但并未影响任务的性能。
