  - XMM-Newton AO-9 long term plan
  - XSA v6.5 release with access to the incremental versions of:
   . the Second XMM-Newton Serendipitous Source Catalogue: 2XMMi-DR3
   . the XMM-Newton Slew Survey Catalogue: XMSL1 Delta-4

XMM-Newton AO-9 long term plan

The scheduling  of the ninth  cycle of XMM-Newton  observations, AO-9,
will start in May  2010 and is expected to finish at  the end of April

On the  28th of April, the  long-term  scheduling  plan  for the  AO-9
period has been released at:


Principal  Investigators   of  pending  XMM-Newton   observations  are
encouraged to  check this  plan, especially if  scheduling constraints
were    granted    following    the    Time    Allocation    Committee
recommendations. All observers should be aware that, as flexibility is
required  in the  scheduling process,  the long  term plan  only fills
about  50% of  the available  observing time,  using some  50%  of the
approved  observations.   Consequently   about  50%  of  the  approved
  observations do not appear in  the long term plan. The final observing
plan is only available some two to four weeks in advance  of the start
of an XMM-Newton  revolution.  It is intended to  follow the long term
plan as closely as  possible. The XMM-Newton SOC nevertheless reserves
the right to  modify the plan at any stage  of the scheduling process,
should this become necessary.

XSA v6.5 release with access to the new 2XMMi-DR3 and XMMSL1 Delta-4

A  new version  of the  XMM-Newton  Science Archive  (XSAv6.5) is  now
available at:


It includes,  among other, improvements  in the search  facilities and
target classification with all the previously unclassified targets now
being classified according to the HEASARC class

XSAv6.5 also  allows users  to access the  incremental version  of the
Second XMM-Newton  Serendipitous Source Catalogue,  2XMMi-DR3, and the
Delta-4 XMM-Newton Slew Survey source catalogue.

Incremental version of the Second XMM-Newton Serendipitous Source
Catalogue: 2XMMi-DR3

A new  incremental version (2XMMi-DR3)  of the second  XMM-Newton EPIC
Serendipitous Source Catalogue, 2XMM,  is being released with XSAv6.5.
It  contains ~353000 detections  of ~263000  unique sources  from 4953
observations (i.e.   836 more observations than  the predecessor 2XMMi
catalogue) that were public by  October 31st 2009.  2XMMi-DR3 covers a
total sky area, with at least 1 ksec exposure, of ~814 square degrees,
or  ~504 square  degrees if  overlaps  are taken  into account.   This
represents an increase of approximately 19% in terms of unique sources
compared with  2XMMi, released  in August 2008.   Of the  total, 30470
detections  are classified as  extended, and  spectra and  time series
have been extracted for 56017 detections, 3177 of which are considered
to  be   variable.   The  positional  uncertainty   of  the  catalogue
detections is generally <  5 arcseconds.  Typical sensitivities in the
catalogue  are  ~6x10E-15 and  ~1.5x10E-14  (ergs/cm2/s)  in the  soft
(0.2-2 keV) and hard (2-12 keV) X-ray band, respectively.

The creation of the 2XMMi-DR3 catalogue is a joint venture carried out
by the SSC  consortium. Details of the catalogue,  the catalogue files
and full 2XMMi-DR3 documentation are available at:


FITS files containing summary  information about the observations used
in the  catalogue and the targets  of those observations  will also be

FITS and CSV  versions of the full 2XMMi-DR3  catalogue and a slimline
version  of  the  FITS  file   are  also  available  for  download  at
http://xmm.esac.esa.int/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, 2XMMi-DR3 will become also available

Incremental version of the XMM-Newton Slew Survey Catalogue:
XMMSL1 Delta-4

An update  to the  XMM-Newton Slew Survey  Catalogue (Delta-4)  is now
available. It can be accessed and searched with XSAv6.5, or downloaded
as a FITS table from the XSA web page above.

The  update   contains  data   from  151  slew   observations  between
revolutions 1673 and 1863. It covers 5725 square degrees, and contains
5514 new detections and 2185 new sources in  the clean catalogue.  The
total sky coverage of the slew catalogue is now around 47%.

Documentation about the catalogue is available at:
