爱因斯坦天文台（HEAO-2，1978年11月13日发射）通过使用聚焦光学器件，实现了比以前的X射线任务更高的灵敏度，同时大大减少了背景并产生了真实的图像。在其为期2.5年的使命中，爱因斯坦X射线望远镜指向了大约5,000个天体目标，其中大部分被探测到，并在观测场中发现了数千个额外的“偶然”源。该目录包含等高线图和源数据，获得与成像比例计数器在0.16至3.5千电子伏的能量带，并描述了恢复上限的方法，为任何天空位置内观察到的图像。主星表由六卷（编号2至7）赤Ascension排序页组成，每卷包含一次观测的数据。沿着描述星表如何构建的主要文档，第1卷包含完整的源列表，合并字段的结果，已发表论文的参考系统，以及用于计算上限和通量的数据。
The Einstein Observatory (HEAO-2, launched November 13, 1978) achieved radically improved sensitivity over previous x-ray missions through the use of focusing optics, which simultaneously afforded greatly reduced background and produced true images. During its 2.5-yr mission, the Einstein X-Ray Telescope was pointed toward some 5,000 celestial targets, most of which were detected, and discovered several thousand additional 'serendipitous' sources in the observed fields. This catalog contains contour diagrams and source data, obtained with the imaging proportional counter in the 0.16 to 3.5 keV energy band, and describes methods for recovering upper limits for any sky position within the observed images. The main catalog consists of six volumes (numbered 2 through 7) of right ascension ordered pages, each containing data for one observation. Along with the primary documentation describing how the catalog was constructed, volume 1 contains a complete source list, results for merged fields, a reference system to published papers, and data useful for calculating upper limits and fluxes.
