Alongside all XMM-Newton scientific data products and observation-related information, high-level catalogues and
a multiwavelength datasets can be accessed through the
XSA user interface or downloaded from the links below:
The XSA v8.2, released on 27 February 2014, provides for the first time access
to two new versions of catalogues: the incremental XMMSL1_Delta6 and the
XMM-SUSS2. It also provides access to new
mosaic ODF subsets generated in 2014, and continues giving access, as earlier
XSA v8 versions, to the 3XMM-DR4 and to all XMM-Newton ODF and PPS files,
either routinely processed since July 2013, or earlier data reprocessed in 2013.
XSA version 8.0:
The XSA v8.0, released on 23 July 2013, offered for the first time a web based
interface to the XMM-Newton Science Archive.
The XSA was fully re-engineered also greatly improving the search speed.
Since v8.0 of the XSA access is provided to all XMM-Newton data including the fully
reprocessed PPS products, and the 3XMM-DR4 catalogue.
Since the release of the web based XSAv8.0 in July 2013
new AIO client files
need to be downloaded in order to get command line access to the new XMM-Newton data.
XSA v7.2 java interface
and associated old AIO client files still work but they
do not provide access to the updated EPIC, Slew Survey and OM catalogues,
to the full reprocessed pipeline products or to the data ingested afterwards.
Moreover the old interface and AIO client files will no longer work after autumn 2014.
Search on a file with a list of positions is currently limited to about 420 positions.
Longer lists give an "Empty file" error message.
A possible workaround to perform a search on a larger list is
to use TOPCAT or
to cross-match your list with the complete
list of XMM-Newton observed positions. This list can be downloaded from
XSA (with no constrain), from
Vizier or from the
XSA observations log.
The observations performed in mosaic mode have a global Observation Data File (ODF)
which is also split into 'pseudo ODFs' (see Chapter 2 of the
Data Files Handbook).
The ObsID of all 'pseudo ODFs' belonging to a mosaic have the first 8 digits in common
(e.g. 06730001). Split 'pseudo ODFs' can be recognised because the last two digits of their
ObsIDs are not 01 but 31, 32, 33, etc. (e.g. 0673000131, 0673000132 etc). Note that the data
(i.e. the X-ray events) of the 'pseudo ODF' subsets is extracted from the global ODF
(i.e. the same data for the sky area covered in the pseudo ODF). Pseudo ODF subsets should
therefore never be combined or merged with the global ODF.
The positions (RA, Dec) of the split ODFs of the mosaic observations up to
revolution 2361 are not displayed correctly in the XSA. The positions displayed are the
ones of the first field observed, therefore mosaic observations are not found in a standard
search in the FOV or in a circle of 15 arcmin radius.
Example: for all the 'pseudo ODFs' 06730001nn XSA displays RA= 22h 19m 45.29s,
Dec= +00d 39' 32.3", therefore searching e.g. for the position RA=22h 15m 54s, Dec=+00d 11' 19"
of the 'pseudo ODF' 0673000141, returns no result.
Publications using XMM-Newton data are updated in the XSA archive up to March 2013.
References using XMM-Newton data are regularly updated in
with links to observations in XSA when applicable.
The on-the-fly data processing functionality has not yet been implemented.
