Chandra X-ray Observatory Stack acisfJ1001467p690129_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".钱德拉源编目（Chandra Source Catalog，CSC）采用合并（即重叠）的钱德拉观测数据来探测X射线源（X-ray sources）。这使得该编目能够收录远比CSC 1.1暗弱的源。以该方式合并的重叠观测数据集被称为"堆叠（stack）"。
