Chandra Source Catalog
Scientific paper
We have cross-matched the Chandra Source Catalog (CSC) with the Sloan Digital Sky Survey (SDSS) DR-7 source catalog using a cross-matching algorithm developed by one of us (TB) and previously applied to a cross-match of SDSS with GALEX catalogs. It is a Bayesian method that takes into account the positions, position errors, as well as the detailed footprints of the catalogs, and provides a Bayesian Factor and an associated probablity for each match. Various tests indicate that cross-matches with probabilities >0.5 are solid and can be trusted; below that value the number of multiple matches increases rapidly. 9020 CSC sources are matched with sources that SDSS considers stars, 7852 with sources considered galaxies. Approximately 150 of these CSC sources appear in both categories. The total area of the footprint intersections is 132.86 square degrees, approximately 45% of the CSC coverage. Both projects, CXC and SDSS, will provide user access to the cross-match database.We shall present details of the cross-match, an interface to it, and some initial statistical science results. This work is supported by NASA contract NAS8-03060 (CXC) and the Sloan Digital Sky Survey Collaboration.
