Description:
The 3XMM-DR7 catalogue contains source detections drawn from 9710
XMM-Newton EPIC observations, covering an energy interval from 0.2keV
to 12keV. These observations were made between 2000 February 3 and
2016 December 15 and all datasets were publicly available by 2016
December 31, but not all public observations are included in this
catalogue (see below for more information).
Should you use the catalogue for your research and publish the
results, please use the acknowledgement below and cite the paper
describing 3XMM (Rosen, Webb, Watson et al., 2016A&A...590A...1R).
This research has made use of data obtained from the 3XMM XMM-Newton
serendipitous source catalogue compiled by the 10 institutes of the
XMM-Newton Survey Science Centre selected by ESA.
The following table gives an overview of the statistics of the
catalogue in comparison with the 3XMM-DR6 catalogue.

The production and content of the 3XMM catalogue is described in the
the 3XMM-DR7 User Guide at
http://xmmssc.irap.omp.eu/Catalogue/3XMM-DR7/3XMM-DR7_Catalogue_User_Guide.html
The slimline version of the catalogue ( file "xmm3r7s.dat") contains
one row per unique source (while the the main catalogue has one row
per detection) and thus has 499266 rows. There are 44 columns,
essentially those containing information about the unique sources. The
catalogue also contains a column with links to the IRAP catalogue
server summary pages. 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.
