中国古天文基础参考星表

中国古天文基础参考星表是一个全天亮星基础数据表，以依巴谷星表为基础，汇集HIP2和XHIP等数据集的恒星参数信息，并归算到J2000.0历元。恒星的选择是亮于7等，合计15537颗恒星。星表包含有J2000.0历元的坐标信息，以及最新的自行、视向速度等数据，可方便用于回推不同历史时期恒星在空间的位置，为古星表的认证以及绘图提供方便。星表以FITS和CSV两种格式提供。

The Basic Reference Star Catalog for Ancient Chinese Astronomy is a fundamental all-sky bright star data table. Based on the Hipparcos Catalog, it collects stellar parameter information from datasets such as HIP2 and XHIP, and is reduced to the J2000.0 epoch. The selected stars are brighter than 7 magnitude, totaling 15,537 stars. The catalog contains coordinate information at the J2000.0 epoch, as well as up-to-date data including proper motion and radial velocity, which can be conveniently used to back-calculate the spatial positions of stars across different historical periods, thus facilitating the authentication and plotting of ancient star catalogs. The catalog is provided in both FITS and CSV formats.
