ROSAT X射线卫星数据

1990年6月1日，德国的X射线天文台ROSAT从美国的卡纳维拉尔角发射升空，揭开了X射线天文学的一个新时代。ROSAT任务最重要的科学目的是：一，完成首次X射线和远紫外望远镜成像全天巡天；二，对X射线选和远紫外选源进行细致的研究。卫星于1999年2月12日停止观测。全天巡天数据于2000年3月11日发布，所有数据于2001年3月9日对外公布。

ROSAT得到了大量有很高科学价值的观测数据。数据的处理维护和发布由德国马普地外物理研究所负责。国内天文界和马普地外物理研究所有着良好的合作关系，ROSAT数据在中国得到充分的利用，是迄今为止中国天文学家使用得最多的国外数据之一。目前中国天文数据中心拥有的ROSAT数据包括全天巡天星图和星表，数据量为32GB，通过50张CD-ROM发行，已经实现在线服务。

On June 1, 1990, Germany's X-ray observatory ROSAT was launched from Cape Canaveral, United States, ushering in a new era for X-ray astronomy. The primary scientific goals of the ROSAT mission were two-fold: 1) to carry out the first all-sky imaging survey using X-ray and far-ultraviolet telescopes; 2) to conduct detailed investigations of X-ray-selected and far-ultraviolet-selected celestial sources. The observatory ceased scientific operations on February 12, 1999. The all-sky survey dataset was released on March 11, 2000, and the full dataset archive was made publicly available on March 9, 2001.

ROSAT has generated a vast amount of observational data of exceptional scientific significance. The processing, curation, and distribution of these data are overseen by the Max Planck Institute for Extraterrestrial Physics (MPE), Germany. The Chinese astronomical community has maintained strong collaborative relations with MPE, and ROSAT data has been fully utilized in China, making it one of the most frequently used foreign datasets by Chinese astronomers to date. Currently, the ROSAT datasets held by the Chinese Astronomical Data Center include all-sky survey maps and catalogs, with a total size of 32 GB, distributed via 50 CD-ROMs, and online access services for these data have been implemented.
