Description:
The Chandra Source Catalog (CSC) is the definitive catalog of X-ray
sources detected by the Chandra X-ray Observatory. By combining
Chandra's sub-arcsecond on-axis spatial resolution and low
instrumental background with consistent data processing, the CSC
delivers a wide variety of uniformly calibrated properties and science
ready data products for detected sources over four decades of flux.
The second major release of the catalog, CSC 2.0, includes measured
properties for 317,167 unique compact and extended X-ray sources in
the sky, allowing statistical analysis of large samples, as well as
individual source studies.
The sensitivity limit for compact sources in CSC 2.0 is 5 net counts
(a factor of > 2 better than the previous catalog release). This
improvement is achieved by using a two-stage approach that involves
co-adding multiple observations of the same field prior to source
detection, and then using an optimized source detection method.
Acknowledging the Chandra Source Catalog in publications:
