Release of the new version of the XMM-Newton OM Catalogue (XMM-SUSS4)

The fourth version of the XMM-Newton Optical Monitor (OM) Serendipitous Ultraviolet Source Survey Catalogue (XMM-SUSS4) has been released.

This version contains observations obtained from 2000 to July 2017. All data have been fully processed using the XMM Science Analysis Software (SAS) system version 17.0. The most recent Time Dependent Sensitivity Degradation correction, issued in June 2018, has been applied to all data.

The total number of entries is 8.17 million. They correspond to 5.50 million sources, of which 1.03 million have multiple entries in the source table, corresponding to different observations. The number of observations included in the catalogue is 9749.

The XMM-SUSS4 catalogue can be accessed through the XSA search interface. Besides, both the complete catalogue and a reduced version can be downloaded from the XSA web page:


XSA v10.2 release with access to the XMM-SUSS4 Catalogue

A new version of the XMM-Newton Science Archive (XSA v10.2) is available at


New in this release is the use of the actual EPIC footprint of the observation for searches within the Field of View (previous versions used a circle of 18 arcmin radius). This results in more precise searches.

Also, the fast web access, previously only possible for 3XMM-DR8, is now available for all the catalogues.

XSA v10.2 provides access to the new version of the OM Catalogue (XMM-SUSS4).


Yours sincerely,
