康普顿伽玛射线天文台上的EGRET望远镜探测到的高能伽玛射线源的第三个目录包括从1991年4月22日到1995年10月3日（任务的第1,2,3和4周期）的数据。除了包含比第二个EGRET目录及其补充目录更多的数据外，该目录还使用完全重新处理的数据（以纠正许多大多数最小的错误和问题）。目录中的271个源（E > 100 MeV）包括1991年一个足够亮的太阳耀斑，大麦哲伦星云，5颗脉冲星，一个可能的射电星系探测（Cen a），以及66个高可信度的blazars （BL Lac天体，平谱射电类星体，或未识别的平谱射电源）。此外，还发现了27个置信度较低的潜在耀变体。最后，该目录包含了170个来源，这些来源尚未被确定为已知的物体，尽管其中一些可能被认为是可能的。图中给出了天空中任意点的伽玛射线源的近似上限，以及在第二目录及其补充中列出的未在本目录中出现的伽玛射线源的信息。
The third catalog of high-energy gamma-ray sources detected by the EGRET telescope on the Compton Gamma Ray Observatory includes data from 1991 April 22 to 1995 October 3 (cycles 1, 2, 3, and 4 of the mission). In addition to including more data than the second EGRET catalog and its supplement, this catalog uses completely reprocessed data (to correct a number of mostly minimal errors and problems). The 271 sources (E > 100 MeV) in the catalog include the single 1991 solar flare bright enough to be detected as a source, the Large Magellanic Cloud, five pulsars, one probable radio galaxy detection (Cen A), and 66 high-confidence identifications of blazars (BL Lac objects, flat-spectrum radio quasars, or unidentified flat-spectrum radio sources). In addition, 27 lower confidence potential blazar identifications are noted. Finally, the catalog contains 170 sources not yet identified firmly with known objects, although potential identifications have been suggested for a number of those. A figure is presented that gives approximate upper limits for gamma-ray sources at any point in the sky, as well as information about sources listed in the second catalog and its supplement, that do not appear in this catalog.
