Chandra Data Archive

The Chandra Data Archive (CDA) plays a central role in the operation of the Chandra X-ray Center (CXC) by providing support to the astronomical community in accessing Chandra data. Its primary role is one of storage and distribution of all data products including those that users of the observatory need to perform their scientific studies using Chandra data. The CDA offers access to digital archives through powerful query engines, including VO-compliant interfaces. The CDA also serves as a permanent storage repository of contributed data products by authors who have processed images or other pertinent and valuable datasets that are essential to their publications.
