Chandra X-ray Observatory Stack acisfJ0536179p340755_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".钱德拉源目录（Chandra Source Catalog, CSC）采用经叠加（即重叠）处理的钱德拉（Chandra）望远镜观测数据开展X射线源探测工作。此方案使得本目录能够收录显著暗于CSC 1.1版本的天体源。以该方式组合的重叠观测集合被称为“堆叠（stack）”。
