The XMM-Newton Survey Science Centre produces catalogues of all X-ray sources detected with XMM-Newton. All catalogues up to 3XMM-DR4 were produced by the University of Leicester in collaboration with the other SSC institutes. Links to all the catalogues can be found on these pages. Ulterior catalogues are produced at the Institut de Recherche en Astrophysique et Planétologie in Toulouse, in collaboration with the other SSC institutes and the XMM-Newton Science Operations Centre (SOC). Catalogues based on a reprocessing of all the data used are named 1XMM, 2XMM, 3XMM, 4XMM, etc. Incremental versions of these catalogues are also released on a regular basis and these include data that has become public since the release of the previous catalogue and processed with a similar, but not necessarily identical, version of the SAS. For the 3XMM-DR7, 4XMM-DR9 and 4XMM-DR10 versions we also provide a stacked version of the catalogue known as 3XMM-DR7s, 4XMM-DR9s and 4XMM-DR10s. All information concerning the data reduction steps can be found on the web pages provided for each catalogue version. Complimentary information is provided in the 2XMM paper (

The stacked catalogue is browsable via the web-based interfaces
Should you have any issues that you wish to raise concerning the X-ray catalogue, please send an email to Natalie Webb with the title '4XMM catalogue issues'.
We also propose a spectral-fit database that proposes simple spectral fits for 146825 detections (99356 sources) in the 3XMM-DR6. Access to the information describing the catalogue can be found on the XMM-Newton spectral-fit database webpage and the database is held here (3XMMSPECTRAL).
We also help produce the XMM-Newton Optical Monitor (OM) Serendipitous Ultra-violet Source Survey Catalogue (XMM-SUSS, Page et al. (2012)). The latest version, XMM-SUSS5 contains 8.86 million detections (5.97 million unique sources). It can be queried at:
