CSC2.0 vs SDSS crossmatch catalog
The Chandra Source Catalog team is pleased to announce that the catalog of crossmatched Chandra Source Catalog 2.0 sources and Sloan Digital Sky Survey (SDSS) DR15 sources is now publicly available
. This probabilistic catalog has been produced using a Bayesian method specifically modified for X-ray source that takes into account elliptical position errors, and includes both unique and ambiguous matches, with a matching probability associated with each potential match. CSC2.0 crossmatches with other multi-wavelength catalogs will be posted to the same webpage in the future.
