- XMM-Newton AO-9 long term plan

. 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
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
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
Alongside the XSA user interface, 2XMMi-DR3 will become also available
Incremental version of the XMM-Newton Slew Survey Catalogue:
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:
