Chandra X-ray Observatory Stack acisfJ1010072p033150_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（钱德拉源目录）使用合并（即重叠）的钱德拉观测数据来检测X射线源。这使得该目录能够包含比CSC 1.1显著更暗的源。以这种方式合并的重叠观测数据集被称为“堆叠（stack）”。
