Beginning of ReadMe : IX/46 XMM-Newton Serendipitous Source Catalogue 3XMM-DR5 (XMM-SSC, 2016) ================================================================================ The XMM-Newton serendipitous survey. VII. The third XMM-Newton serendipitous source catalogue. Rosen S.R., Webb N. A., Watson, M.G., Ballet J., Barret D., Braito V., Carrera F.J., Ceballos M.T., Coriat M., Della Ceca R., Denkinson G., Esquej P., Farrell S.A., Freyberg M., Grise F., Guillout P., Heil L., Law-Green D., Lamer G., Lin D., Martino R., Michel L., Motch C., Nebot Gomez-Moran A., Page C.G., Page K., Page M., Pakull M.W., Pye J., Read A., Rodriguez P., Sakano M., Saxton R., Schwope A., Scott A.E., Sturm R., Traulsen I., Yershov V., Zolotukhin I. <XMM-SSC, Leicester, UK; Astron. Astrophys. 590, A1 (2016)> =2016yCat.9046....0R =2016A&A...590A...1R ================================================================================ ADC_Keywords: X-ray sources ; Surveys Mission_Name: XMM Keywords: catalogs - astronomical data bases - surveys - X-rays: general 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.
