Chandra X-ray Observatory Stack hrcfJ1737179m425926_001

CSC uses combined (i.e. overlapping) Chandra observations for detecting X-ray sources. This allows the catalog to include significantly fainter sources than CSC 1.1. The set of overlapping observations that have been combined in this way is known as a "stack".CSC采用组合（即重叠）的钱德拉（Chandra）观测数据开展X射线源探测。这使得该星表可收录远较CSC 1.1暗弱的X射线源。以该方式组合的重叠观测数据集被称为‘堆叠（stack）’。
