Detailed Description of CXC/V2 : Chandra Catalog Release View

 |
Note : this is the description file of the original catalog.
This HTML page corresponds well to the original description, but some minor
changes in the format may have been introduced in the FITS output
files in order to allow for arithmetic operations on quantities
such as coordinates and times. h:m:s and d:m:s units are normally
converted into degrees, and YYYY-MM-DD into julian days.
Similarly, some slight changes may have been introduced in the
units; the value given in the HTML files supersedes the value indicated in the ReadMe
file for this catalogue.

Description:
The Chandra Source Catalog (CSC; http://cxc.cfa.harvard.edu/csc/) is ultimately intended
to be the definitive catalog of X-ray sources detected by the Chandra X-ray Observatory.
The current version of the catalog is release 1.1. This version includes the information
contained in release 1.0.1, plus point and compact source data extracted from HRC imaging
observations, and catch-up ACIS observations released publicly prior to the end of 2009.
Users who wish to reference the Chandra Source Catalog in a publication should cite
Evans, I.N., et al. 2010, ApJS, 189, 37 or Evans, I.N., et al. 2010, arXiv:1005.4665
The version employed at Strasbourg Observatory/CDS uses the results of a VO Cone Search
(http://cda.cfa.harvard.edu/cscvo/coneSearch) on source position in the released CSC.
The Search with VERB (verbosity) parameter 2 returns the master source summary results
and Space Time Coordinate (STC) metadata for each matching source. It includes 24 CSC
master source properties listed in the Description of the Catalog below.
We thank the CSC team for their kind permission to correlate their catalog with
the results obtained by XMM/Newton.
