XSA v10.0 release including access to the 3XMM (DR8) Catalogue
--------------------------------------------------------------
A new version of the XMM-Newton Science Archive (XSA v10.0) is available
at
https://www.cosmos.esa.int/web/xmm-newton/xsa
There are two main changes in this version: it provides access to the
incremental version of the 3XMM Catalogue (DR8, see next item in this
newsletter) and it uses a new image viewer for the interactive data
analysis functionality (done via the Remote Interface for Science
Analysis, RISA, as announced in Newsletter#198). The new image viewer is
JS9 (https://js9.si.edu/) replacing DS9 and integrated in the web
browser, making its usage more straightforward. In addition, the new XSA
version contains now the Radiation Monitor files and allows select and
download of these data.
Release of the new version the XMM-Newton Serendipitous Source
Catalogue: 3XMM (DR8) and new outreach pages
--------------------------------------------------------------
A new version of the XMM-Newton EPIC Serendipitous Source Catalogue,
3XMM-DR8, has been released. The catalogue includes an extra year of
data with respect to 3XMM-DR7, with 775153 X-ray detections which relate
to 531454 unique X-ray sources from 10242 observations that were public
by the 31st December 2017. 3XMM-DR8 covers a total sky area, with at
least 1 ks exposure, of ~1089 square degrees if overlaps are taken into
account, where some regions of the sky have been pointed as many as 59
times. 3XMM-DR8 is an increase of approximately 7% in terms of unique
sources compared with 3XMM-DR7, that was released in June 2017. Around
9% 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 1.6
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 band, respectively.
The creation of the 3XMM Catalogue is a joint venture carried out by the
XMM-Newton Survey Science Centre (XMM-SSC) 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 on the XMM-SSC webpages at
http://xmmssc.irap.omp.eu/Catalogue/3XMM-DR8/3XMM_DR8.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
http://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
XCATDB ..... http://xcatdb.unistra.fr/3xmmdr8/
HEASARC .... http://heasarc.gsfc.nasa.gov/W3Browse/xmm-newton/xmmssc.html
IRAP ....... http://xmm-catalog.irap.omp.eu/
LEDAS ...... http://www.ledas.ac.uk/
This catalogue, along with the other catalogues produced in the
framework of ESA's XMM-Newton mission, will be presented at the workshop
'Treasures hidden in high energy catalogues' that will take place at
IRAP, Toulouse, France, from the 22nd to the 24th May 2018. Please see
the website for further details
https://catalogue-gems.sciencesconf.org/
With the release of the 3XMM-DR8 catalogue XMM-SSC also releases new
webpages aimed at the general public of all generations. These pages
are a complement to the existing webpages, and can be found at
http://xmm-ssc.irap.omp.eu
Yours sincerely,
XMM-Newton SOC
