New XMM-Newton catalogues are created on a regular basis. The latest 3XMM-DR4 was released in July 2013.
3XMM-DR4 contains around 531,000 detections (373,000 unique
sources) drawn from 7427 XMM-Newton observations
that were public by December 31st 2012 and covers a unique sky area of
794 square degrees. This represents about a 50% increase in size over
its predecessor, 2XMMi-DR3. Typical sensitivities in the 3XMM-DR4 catalogue
are 6 10 and 1.3 10 erg cm s in
the soft and hard X-ray bands, respectively. XMM-Newton observers may find
the 3XMM-DR4 catalogue useful in planning new observation
proposals. Further details of each XMM-Newton EPIC catalogue, including
available formats, access methods and the Catalogue User Guides, are
available through links from the Catalogues home page, at:
A paper describing the previous 2XMM catalogue is available (Watson et al., 2009, A&A, 493, 339) - while the 3XMM-DR4 catalogue includes a number of significant enhancements to the data processing, which are described in the on-line 3XMM-DR4 documentation, many elements of the paper remain pertinent to the production of the 3XMM-DR4 catalogue.
The catalogue can also be retrieved from the XMM-Newton Science Archive web page in FITS or CSV format and is fully accessible through XMM-Newton Science Archive user interface.
Other useful interfaces to the 3XMM-DR4 catalogue include
the XCAT-DB at
the HEASARC interface at
which are particularly useful for exploring correlations with other catalogues.
