Schedule and Status

The first batch of data from release 2.0 of the CSC has been made available to the community as the Preliminary Detections List. This data set will be updated over time.

Processing of Chandra Source Catalog Release 2 has started.

Co-adds multiple observations of the same field that use the same instrument prior to source detection, to achieve fainter limiting sensitivities, as well as providing improvements in extended source handling.

Chandra Source Catalog Release 1.1

Extends Release 1 to include public HRC-I imaging observations, and newly public ACIS observations, but otherwise retains the same limitations as Release 1.

Chandra Source Catalog Release 1

Includes information about sources detected in a subset of ACIS imaging observations released publicly prior to the end of 2008. Only point and compact sources, with observed spatial extents < ~30 arcsec, are included. Multiple observations of the same field are not co-added prior to performing source detection.
