Chandra X-ray Observatory Stack acisfJ1046443m360109_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采用经联合整合的重叠钱德拉（Chandra）观测数据来探测X射线源。此举使得该源目录能够收录远较CSC 1.1版本暗弱得多的X射线源。以该方式组合的重叠观测数据集，被称为"堆叠（stack）"。
