A..3.1 3XMM-DR4

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 ($\simeq $373,000 unique sources) drawn from $\sim $ 7427 XMM-Newton observations that were public by December 31st 2012 and covers a unique sky area of $\sim $ 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 $\times $ 10$^{-15}$ and 1.3 $\times $ 10$^{-14}$ erg cm$^{-2}$ s$^{-1}$ 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:
http://xmmssc-www.star.le.ac.uk/Catalogue/.
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 LEDAS, e.g.,

the XCAT-DB at
http://xcatdb.unistra.fr,
the HEASARC interface at
http://heasarc.gsfc.nasa.gov/W3Browse/xmm-newton/xmmssc.html
which are particularly useful for exploring correlations with other catalogues.
