XSA v8.0 release with access to the 3XMM (DR4) and full reprocessed data

A  new, completely  re-engineered  version of  the XMM-Newton  Science
Archive (XSA v8.0) has been released. Details are available at the XSA
web page:


Additionally,  XSA v8.0  also allows  access to  the  third generation
XMM-Newton Serendipitous  Source Catalogue 3XMM (DR4) and to the full
uniform reprocessing of all XMM-Newton  data up to December 2012, with
homogeneous software and calibration.

* Release of the new version of the XMM-Newton Serendipitous Source
  Catalogue: 3XMM (DR4)

A new  version of the XMM-Newton EPIC  Serendipitous Source Catalogue,
3XMM,  is  now  released.  The   catalogue  is  based  on a  complete
reprocessing  of  the XMM-Newton  data  using  an enhanced processing
pipeline  which  includes  a  wide  range of improvements.  The  3XMM
catalogue thus supersedes the previous 2XMMi-DR3 release.

The  3XMM  catalogue contains  ~531000  detections  of ~373000  unique
sources from 7427 observations that were public by 31st December 2012.
3XMM covers  a total sky area, with  at least 1 ks exposure, of ~1400
square  degrees, or  ~800 square  degrees if  overlaps are taken into
account.  This represents an increase of approximately 50% in terms of
unique  sources  compared  with  2XMMi-DR3, released  in April  2010.
Around 10% of  the detections are classified as  extended, and spectra
and time  series have  been extracted for  around 45% of the sources.
The positional  uncertainty of  the catalogue detections is generally
less than 3 arcseconds (90% confidence) and the astrometric quality of
3XMM  is   improved  with  respect  to   previous releases.   Typical
sensitivities in the catalogue are ~6x10E-15 and ~1.5x10E-14 erg/cm2/s
in the soft (0.2-2 keV) and hard (2-12 keV) X-ray band, respectively.

The creation of  the 3XMM catalogue is a joint  venture carried out by
the SSC Consortium. Details of  the catalogue, the catalogue files and
full 3XMM documentation are available at


FITS files containing summary  information about the observations used
in the catalogue will also be  provided.  FITS and CSV versions of the
full 3XMM catalogue  and a slimline version of the  FITS file are also
available for download at


The slimline version  has only one row per  unique source (rather than
per  detection as  in  the main  catalogue)  and a  reduced number  of
columns that essentially pertain to the unique source quantities.

Alongside  the XSA  user interface,  3XMM will  become also available

* Release of full pipeline-reprocessed XMM-Newton data

The  XMM-Newton Survey  Science  Centre (SSC)  has undertaken,  during
2012, a  full reprocessing of  all XMM-Newton observations.   The 3XMM
source catalogue has been  constructed from public observations during
this reprocessing. This is the second such bulk reprocessing exercise,
the first  one undertaken during 2006/2007.  The complete reprocessing
in  2012 used  an enhanced  processing pipeline  and has generated an
homogeneous set of  pipeline products for all the instruments and all
the observations performed by XMM-Newton until the end of 2012.

This  large  and uniformly  processed  set  of  data products  is  now
accessible through the newly released XSA v8.0.

* XSA v8.0

The XMM-Newton Science Archive has been fully re-engineered for faster
and more  efficient searches of XMM-Newton  data. The data can now be
searched and downloaded using a web-based interface:


or  can  be  accessed  via  command line  scripts  using the  Archive
Interoperability  system (AIO),  which  requires to download new  AIO
client files from


Please note that links to the Postcard server have to be replaced by a
direct link to the ObsID web page, e.g.


XSA v7.2 to be discontinued in a few months

The XSA v7.2 java interface and the old AIO client files will still be
usable  for a  few months  to  allow a  smooth transition to the  new

Astronomers are strongly encouraged to  change to the new XSA v8.0 and
AIO because XSA v7.2 is frozen with no access to new data, to the 3XMM
catalogue, or  to the full reprocessed  pipeline products. Proprietary
rights in XSA v7.2 are also frozen since 8 July 2013.

Please note  that in order to  access the new  XMM-Newton data through
the AIO users need to download  the new AIO client files, as explained
in the previous news item.

Yours sincerely,

XMM-Newton SOC
