- Release of the new version of the XMM-Newton Serendipitous Source
Catalogue: 3XMM (DR7)
XSA v9.5 release with access to the 3XMM (DR7) Catalogue
--------------------------------------------------------
A new version of the XMM-Newton Science Archive (XSA v9.5) is available
at
https://www.cosmos.esa.int/web/xmm-newton/xsa
It includes, among other improvements, access to the incremental version
of the 3XMM catalogue (DR7):
New version of the XMM-Newton Serendipitous Source Catalogue: 3XMM (DR7)
------------------------------------------------------------------------
A new version of the XMM-Newton EPIC Serendipitous Source Catalogue,
3XMM-DR7, has been released. The catalogue includes an extra year of
data with respect to 3XMM-DR6, with 727790 detections which relate to
499266 unique sources from 9710 observations that were public by the
31st December 2016. 3XMM-DR7 covers a total sky area, with at least 1 ks
exposure, of ~1032 square degrees if overlaps are taken into account,
where some regions of the sky have been pointed as many as 59
times. 3XMM-DR7 represents an increase of approximately 7% in terms of
unique sources compared with 3XMM-DR6, that was released in July
2016. Around 12% of all the detections are classified as extended, and
spectra and time series have been extracted for around 22% of the
sources. The median positional uncertainty of the catalogue detections
is 1.7 arcseconds (with a standard deviation of 1.39) and the
astrometric quality of 3XMM is improved with respect to prior releases.
Median sensitivities in the catalogue are ~6E-15 and ~8E-15 erg/cm2/s in
the soft (0.2-2 keV) and hard (2-12 keV) X-ray bands, respectively.
The creation of the 3XMM catalogue is a joint venture carried out by the
XMM-Newton Survey Science Centre Consortium. The catalogue is described
in the paper Rosen, Webb, Watson et al. 2016, A&A, 590, 1. Details of
the catalogue, the catalogue files and full 3XMM documentation are
available at
http://xmmssc.irap.omp.eu/Catalogue/3XMM-DR7/3XMM_DR7.html
FITS files containing summary information about the observations used in
the catalogue are also provided. FITS and CSV versions of the full 3XMM
catalogue and a slimline version of the FITS file are also available for
download at
https://www.cosmos.esa.int/web/xmm-newton/xsa
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 is also distributed through:
