The XMM-Newton Science Archive (XSA) became publicly available in April 2002. The XMM-Newton Science Archive content is regularly updated with all the generated ODFs, SDFs and PPS products and with updated versions of the catalogues of EPIC sources, OM sources and Slew Survey sources.
Public data can be retrieved through the XSA user interface: http://nxsa.esac.esa.int/nxsa-web/. Data can also be retrieved directly from the archive via URL or command line (see examples at the Archive Inter Operativity system, AIO, http://nxsa.esac.esa.int/nxsa-web/#aio). XSA database tables can be queried using ADQL (Astronomical Data Query Language), see the Table Access Protocol, tap (http://nxsa.esac.esa.int/nxsa-web/#tap) for details.
PIs of XMM-Newton observations can retrieve their own proprietary data using their password-protected XSA account.
In 2012-13 the SSC performed the second bulk reprocessing of all XMM-Newton data obtained since the beginning of the mission in 1999, and all data are thus processed with SAS 12.0 or higher.
To obtain an upper limit from XMM-Newton slew and/or pointed
observations at a given sky position, there is an Upper Limit
Of interest may also be the http://www.ledas.ac.uk/flix/flix_dr5.html server providing flux
limits from images taken with XMM-Newton; see section A.3.2.
