Chandra X-ray Observatory Stack acisfJ1429150p154629_002

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（钱德拉源星表）采用合并后的（即视场重叠的）钱德拉（Chandra）观测数据开展X射线源探测。相较于CSC 1.1版本，该星表可收录显著更暗弱的X射线源。通过此种方式合并得到的重叠观测数据集，被称为“堆叠（stack）”。
