Abstract:
Thanks to the large collecting area (3x 1500cm^2^ at 1.5keV) and wide
field of view (30' across in full field mode) of the X-ray cameras on
board the European Space Agency X-ray observatory XMM-Newton, each
individual pointing can result in the detection of hundreds of X-ray
sources, most of which are newly discovered. Recently, many
improvements in the XMM-Newton data reduction algorithms have been
made. These include enhanced source characterisation and reduced
spurious source detections, refined astrometric precision of sources,
greater net sensitivity for source detection and the extraction of
spectra and time series for fainter sources, with better
signal-to-noise. Further, almost 50% more observations are in the
public domain compared to 2XMMi-DR3, allowing the XMM-Newton Survey
Science Centre (XMM-SSC) to produce a much larger and better quality
X-ray source catalogue. The XMM-SSC has developed a pipeline to reduce
the XMM-Newton data automatically and using improved calibration a new
catalogue version has been made from XMM-Newton data made public by
2013 Dec. 31 (13 years of data). Manual screening ensures the highest
data quality. This catalogue is known as 3XMM. In the latest release,
3XMM-DR5, there are 565962 X-ray detections comprising 396910 unique
X-ray sources. For the 133000 brightest sources, spectra and
lightcurves are provided. For all detections, the positions on the
sky, a measure of the detection quality, and an evaluation of
variability is provided, along with the fluxes and count rates in 7
X-ray energy bands, the total 0.2-12keV band counts, and four
hardness ratios. To identify the detections, a cross correlation with
228 catalogues is also provided for each X-ray detection. 3XMM-DR5 is
the largest X-ray source catalogue ever produced. Thanks to the large
array of data products, it is an excellent resource in which to find
new and extreme objects.
Description:
The 3XMM-DR5 catalogue is the third generation catalog of
serendipitous X-ray sources from the European Space Agency's (ESA)
XMM-Newton observatory, and has been created by the XMM-Newton Survey
Science Centre (SSC) on behalf of ESA. The catalog has 354 more
observations and 34701 more detections than the preceding 3XMM-DR4
catalog, which was made public in July 2013.
The history of the versions can be summarized as:
----------------------------------------------------
Name DR# Designation Year Cat. #Sources
----------------------------------------------------
2XMMp 0 2XMMp-DR0 2006
2XMM 1 2XMM-DR1 2007 IX/39 191870
2XMMi 2 2XMMi-DR2 2008 IX/40 221012
2XMMi-DR3 3 2XMMi-DR3 2010 IX/41 262902
3XMM-DR4 4 3XMM 2013 IX/44 372728
3XMM-DR5 5 3XMM 2016 IX/46 396910
----------------------------------------------------
The production and content of the 3XMM catalogue is described in the
the 3XMM-DR4 User Guide at
http://xmmssc.irap.omp.eu/Catalogue/3XMM-DR5/3XMM-DR5_Catalogue_User_Guide.html
The "slim" version of the catalogue (file "xmm3r5s.dat") contains one
row per unique source, while the the main catalogue has one row per
detection. This slim version includes 44 columns, essentially those
containing information about the unique sources, while the full
catalogue (file "xmm3r5.fit") describes all detections with 323
columns. The slim version also contains a column with links to
the summary pages in the IRAP catalogue archive.
In the case of sources with multiple detections the summary page of
the best detection is selected (i.e., the detection with the largest
exposure time, summed over all cameras), and the summary page gives
cross-links to the other detections.
A separate file "summary.dat" contains the key details about the
observations used in the construction of the 3XMM-DR5 catalogue.
