Chandra X-ray Observatory Stack acisfJ1814304m170941_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采用合并（即重叠）的钱德拉（Chandra）观测数据开展X射线源（X-ray sources）探测工作。这使得本编目可收录远较CSC 1.1暗弱的天体源。此类以该方式合并的重叠观测集合被称为"堆叠（stack）"。
