宽视场X射线望远镜（WXT）是爱因斯坦探针（EP）任务的主要有效载荷。它利用创新的龙虾眼微孔光学（MPO），实现了大瞬时视场（FoV）和高探测灵敏度的前所未有的结合。精确的科学数据分析从根本上依赖于标准化且强大的校准数据库（CALDB）。本文介绍了WXT CALDB的设计与实现。该数据库旨在管理12个独立WXT模块和48个CMOS传感器的校准数据，纳入了大量地面校准结果和在轨动态更新。详细说明了目录层次结构、命名约定、功能以及关键校准产品的特定格式。WXT CALDB无缝集成到WXT数据分析管道中，确保了高数据完整性并最大化了任务的科学回报。
英文摘要
The wide-field X-ray telescope (WXT) is the primary payload of the Einstein Probe (EP) mission. Utilizing innovative lobster-eye micro-pore optics (MPO), it achieves an unprecedented combination of a large instantaneous field-of-view (FoV) and high detection sensitivity. Precise scientific data analysis relies fundamentally on a standardized and robust calibration database (CALDB). In this paper, we present the design and implementation of the WXT CALDB. The database is designed to manage calibration data for 12 independent WXT modules and 48 CMOS sensors, incorporating both extensive on-ground calibration results and dynamic in-orbit updates. We detail the directory hierarchy, naming conventions, functionality, and the specific formats of key calibration products. The WXT CALDB is seamlessly integrated into the WXT data analysis pipeline, ensuring high data integrity and maximizing the scientific return of the mission.
