Schedule and Status

Current Schedule

September 2008	Start catalog production
October 2008	First public access to catalog database
March 2009	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.
August 2010	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.
2012-2013	Chandra Source Catalog Release 2
	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
