The first XMM-Newton Serendipitous Source Catalogue
from overlapping observations (3XMM-DR7s)

A  new  XMM-Newton  EPIC  Serendipitous  Source  Catalogue  made  from
stacking  individual observations has  been released.   The catalogue,
3XMM-DR7s,  has  been  compiled   from  434  groups,  comprising  1789
overlapping  good-quality  XMM-Newton  observations, which  have  been
selected from  public observations taken  between 2000 February  3 and
2016 December 15.

3XMM-DR7s  contains 71951  unique sources  and additional  216393 rows
with  source parameters  derived for  all observations  at  the fitted
position. The catalogue provides  positions and source parameters such
as fluxes  in the XMM-Newton  standard energy bands,  hardness ratios,
quality  estimate, and  information on  inter-observation variability.
In  addition, auxiliary  data  products have  been  produced for  each
source:  a broad-band  X-ray  image, a  colour-coded three-band  X-ray
image, an optical finding chart, and a long-term X-ray light curve.

3XMM-DR7s covers a  total sky area of ~150  square degrees.  Around 5%
of  the sources  are classified  as extended.   The  median positional
uncertainty of the  catalogue sources is 1.1 arcseconds  with a median
absolute  deviation of  0.4 arcseconds.   Median sensitivities  in the
catalogue are ~1.89E-14  erg/cm2/s in the 0.2-12 keV  band.  About 25%
of the sources have all-EPIC fluxes below 10E-14 erg/cm2/s.

The creation of the 3XMM-DR7s catalogue is a joint venture carried out
by  the XMM-Newton  Survey Science  Centre (XMM-SSC)  Consortium.  The
catalogue is  described in the release  paper by Traulsen  et al. 2018
(submitted to A&A). Details of the catalogue, the catalogue files, and
the full 3XMM documentation are available on the XMM-SSC webpages at


A FITS file containing summary information about the observations used
in the catalogue is provided.  3XMM-DR7s can be browsed and downloaded


Alongside the XSA user interface, 3XMM is also distributed through:

XCATDB.......... http://xcatdb.unistra.fr/3xmmdr7s
HEASARC......... https://heasarc.gsfc.nasa.gov/docs/xmm/xmmgof.html

XSA v10.1 release with access to the 3XMM-DR7s Catalogue

A  new  version of  the  XMM-Newton  Science  Archive (XSA  v10.1)  is
available at


This version includes access to  the 3XMM Stacked Catalogue (DR7s) and
some improved functionalities.

- The interface  allows to search 3XMM-DR7s  Stacked Catalogue sources
  and  to display  their  fluxes  and other  parameters.   It is  also
  possible to  deploy the individual  observations used to  obtain the
  stacked  source  and  to  view  the  parameters  of  the  individual
  detections, if  available.  Stacked  Catalogue sources are  linked to
  the corresponding 3XMM sources, if already detected.

- People  interested in  e.g. observations  containing  only exposures
  obtained  with  CLOSED  filters,  can  select them  by  marking  the
  corresponding button in the Search panel.

- The  XSA Table  Access Protocol  (TAP) schema  has now  a  more user
  friendly view of the query parameters.

XMM-Newton Users' Group:
Minutes of meeting and presentations available

The XMM-Newton  Users' Group met on the  17th and 18th of  May 2018 at
ESAC. The minutes of the meeting, together with the presentations, can
be found at


XMM-Newton Users Handbook update for AO-18

The XMM-Newton Users  Handbook (UHB) has been updated  to version 2.16
in preparation for the  next Announcement of Opportunity (AO-18) which
will open next 21st of August.

The  UHB   contains  information  on  the   instrumentation  on  board
XMM-Newton  and serves  as  the main  technical  support document  for
proposal preparation,  based on  which potential XMM-Newton  users can
assess the technical feasibility of their planned observations.

The XMM-Newton Users Handbook is on-line at


Alternatively,  pdf  and  postscript   versions  of  the  UHB  can  be
downloaded from the "XMM-Newton Proposer's Info and Manuals" portal


Scientific Validation Report for SAS v17.0

The results  of the scientific validation  of the last  version of the
XMM-Newton Science Analysis System, SAS  v17.0 (see issue #211 of this
Newsletter), have been summarised in  a report available under the SAS
Scientific Validation page


Documentation updated:
EPIC and RGS Calibration Status and XMM-Newton Background documents

New versions of the following documents have been released:

- EPIC Calibration Status

- RGS Calibration Status

both available from the XMM-Newton Calibration Portal:


- The Behaviour of the XMM-Newton Background

available from the XMM-Newton Background Analysis page:

Let us know about XMM-Newton related Ph.D.
and prizes for XMM-Newton results

As announced in previous issues of this Newsletter (e.g.  issue #193),
the XMM-Newton team is  collecting information about the completion of
doctorates and  Ph.D.  theses based  on (or making use  of) XMM-Newton

We would  appreciate if you - being  a candidate or a  supervisor of a
doctorate - could let us know details through the page


Also we would be grateful if you could inform us (via a message to
xmmhelp@sciops.esa.int, with subject "Ph.D. thesis work") in case you
are aware of theses from, or supervised by, colleagues that make use
of XMM-Newton data but are not yet included in the above list.

In  addition, the XMM-Newton  SOC would  like to  establish a  list of
prizes won based on XMM-Newton results.  Information about such prizes
can  be  sent  via  e-mail to  the  Helpdesk  (xmmhelp@sciops.esa.int)
indicating  the name  of the  winner,  year, prize  name and  granting

Workshop Announcement:
"INTEGRAL looks AHEAD to Multi-Messenger Astrophysics"

The  12th  INTEGRAL  Conference   and  1st  AHEAD  Gamma-ray  workshop
"INTEGRAL looks AHEAD to Multi-Messenger Astrophysics" will take place
in Geneva (Switzerland) from the 11th to the 15th February 2019.

On August 17  2017, a new era in astronomy was  inaugurated by a short
gamma-ray  burst accompanying  the gravitational  wave  event GW170817
detected  by  LIGO-Virgo.  One  of  the  most important  observational
challenges  of  our  time  is   to  establish  the  link  between  the
discoveries   of  these  new   astronomies  and   the  electromagnetic
Universe. Gamma-ray  astronomy has been,  and will remain,  pivotal in
connecting new and "old" astronomies.

This  conference  will  discuss  recent  developments  in  high-energy
astronomy,  with particular  emphasis on  its role  in multi-messenger
astronomy.  One  of the aims of  the workshop is to  review the status
and development  of future instruments and to  discuss perspectives in
observational gamma-ray astronomy.
