Description:
XMM is the second comprehensive catalogue of serendipitous X-ray sources from the European Space Agency's (ESA) XMM-Newton observatory. The 2XMM catalogue is the largest X-ray source catalogue ever produced, containing almost twice as many discrete sources as either the ROSAT survey or pointed catalogues. 2XMM complements deeper Chandra and XMM-Newton small area surveys, probing a much larger sky area.

Description:
The 3XMM-DR4 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 2474 more observations and about 178,000 (50%) more detections than the preceding 2XMMi-DR3 catalog, which was made public in April 2010. 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 ---------------------------------------------------- The production and content of the 3XMM catalogue is described in the the 3XMM-DR4 User Guide at http://xmmssc-www.star.le.ac.uk/Catalogue/3XMM-DR4/UserGuide_xmmcat.html The "slim" version of the catalogue (file "xmm3r4s.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 "xmm3r4.fit") describes all detections with 318 columns. The slim version also contains a column with links to the LEDAS 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. A separate file "summary.dat" contains the key details about the observations used in the construction of the 3XMM-DR4 catalogue.

Description:
Sky surveys produce enormous quantities of data on extensive regions of the sky. The easiest way to access this information is through catalogues of standardised data products. XMM-Newton has been surveying the sky in the X-ray, ultra-violet and optical bands for 20 years. The XMM-Newton Survey Science Centre has been producing standardised data products and catalogues to facilitate access to the serendipitous X-ray sky. Using improved calibration and enhanced software we re-reduced all of the 14041 XMM-Newton X-ray observations. 11204 observations contained data with at least one detection and with these we created a new, high quality version of the XMM-Newton serendipitous source catalogue, 4XMM-DR9. 4XMM-DR9 contains 810795 detections down to a detection significance of 3{sigma}, of which 550124 are unique sources, that cover 1152-degrees^2^ (2.85%) of the sky. Filtering 4XMM-DR9 to retain only the cleanest sources with at least a 5{sigma} detection significance leaves 433612 detections. 99.6% of these detections have no pileup. 336 columns of information on each detection are provided, along with images. The quality of the source detection is shown to have improved significantly with respect to previous versions of the catalogues. Spectra and lightcurves are also made available for more than 288000 of the brightest sources (36% of all detections).

Description:
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.

IX/40, August 2008) catalogues: 2XMMp was a preliminary version of 2XMM. 2XMMi and 2XMMi-DR3 are incremental versions of the 2XMM catalogue. In summary, the versions are: -------------------------------------------- Name DR# Designation Year Cat. -------------------------------------------- 2XMMp 0 2XMMp-DR0 2006 2XMM 1 2XMM-DR1 2007 IX/39 2XMMi 2 2XMMi-DR2 2008 IX/40 2XMMi-DR3 3 2XMMi-DR3 2010 IX/41 -------------------------------------------- The production and content of the 2XMM catalogue is described in detail in "The XMM-Newton serendipitous survey. V. The second XMM-Newton serendipitous source catalogue", M.G. Watson et al., 2009A&A...493..339W; there are no significant differences in the processing between the 2XMM, 2XMMi and 2XMMi-DR3 observations The "slim" version of the catalogue (file "xmm2r3s.dat") contains one row per unique source, while the the main catalogue has one row per detection. This slim version includes 38 columns, essentially those containing information about the unique sources, while the full catalogue (file "xmm2r3.fit") describes the 353191 detections with 299 columns. The slim version also contains a column with links to the LEDAS 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.

Description:
The XMMSSC table contains the Fourth XMM-Newton Serendipitous Source Catalog, Fourteenth Data Release, or 4XMM-DR14. 4XMM-DR14 is the fourth-generation catalog of serendipitous X-ray sources from the European Space Agency&#39;s (ESA) XMM-Newton observatory, and has been created by the XMM-Newton Survey Science Centre (SSC) on behalf of ESA. It is an incremental version of the the 4XMM catalog and contains 621 more observations and 51,884 more detections than the preceding 4XMM-DR13 catalog, which was made public in July 2023. In addition, the team provides spectra and lightcurves for more than 18,775 more detections than in 4XMM-DR13. The catalog contains source detections drawn from a total of 13,864 XMM-Newton EPIC observations made between 2000 February 1 and 2023 December 31; all datasets included were publicly available by 2023 December 31 but not all public observations are included in this catalog. For net exposure time &gt;= 1ksec, the net area of the catalog fields taking account of the substantial overlaps between observations is ~1,383 deg&lt;sup&gt;2&lt;/sup&gt;. 4XMM-DR13 contains 1,035,832 X-ray detections above the processing likelihood threshold of 6. These X-ray detections relate to 692,109 unique X-ray sources. A significant fraction of sources (135,324, 20%) have more than one detection in the catalog (up to 90 repeat observations in the most extreme case). The catalog distinguishes between extended emission and point-like detections. Parameters of detections of extended sources are only reliable up to the maximum extent measure of 80 arcseconds. There are 96,553 detections of extended emission, of which 22,147 are &#39;clean&#39; (in the sense that they were not flagged). Due to intrinsic features of the instrumentation as well as some shortcomings of the source detection process, some detections are considered to be spurious or their parameters are considered to be unreliable. It is recommended to use a detection flag and an observation flag as filters to obtain what can be considered a &#39;clean&#39; sample. There are 897,091 out of 1,035,832 detections that are considered to be clean (i.e., summary flag &lt; 3). For 372,313 detections, EPIC time series and 372,603 detections, EPIC spectra were automatically extracted during processing, and a chi&lt;sup&gt;2&lt;/sup&gt;-variability test was applied to the time series. 8,380 detections in the catalog are considered variable, within the timespan of the specific observation, at a probability of 10&lt;sup&gt;-5&lt;/sup&gt; or less based on the null-hypothesis that the source is constant. Of these, 6,307 have a summary flag &lt;3. The median flux (in the total photon-energy band 0.2 - 12 keV) of the catalog detections is ~ 2.2 x 10&lt;sup&gt;-14&lt;/sup&gt; erg/cm&lt;sup&gt;2&lt;/sup&gt;/s; in the soft energy band (0.2 - 2 keV) the median flux is ~ 5.2 x 10&lt;sup&gt;-15&lt;/sup&gt;, and in the hard band (2 - 12 keV) it is ~1.2 x 10&lt;sup&gt;-14&lt;/sup&gt;. About 23% have fluxes below 1 x 10&lt;sup&gt;-14&lt;/sup&gt; erg/cm&lt;sup&gt;2&lt;/sup&gt;/s. The flux values from the three EPIC cameras are, overall, in agreement to ~10% for most energy bands. The median positional accuracy of the catalog point source detections is generally &lt; 1.57 arcseconds (with a standard deviation of 1.43 arcseconds). With 4XMM-DR14, the team also released 4XMM-DR14s, available from HEASARC as &lt;a href="/W3Browse/xmm-newton/xmmstack.html"&gt;XMMSTACK&lt;/a&gt;, a new version of the stacked catalog built from 10,336 4XMM-DR14 overlapping observations. 4XMM-DR14s contains 1,751 stacks (or groups). Most of the stacks are composed of 2 observations and the largest has 372. The catalog contains 427,524 sources, of which 329,972 have several contributing observations. Stacking observations allows yet fainter sources to be detected in sky regions observed more than once, increasing the number of detections and uncovering long-term variability on repeatedly observed objects. 4XMM-DR14s reaches a depth of ~2.5 x 10&lt;sup&gt;-15&lt;/sup&gt; and ~6.8 x 10&lt;sup&gt;-15&lt;/sup&gt; erg/cm&lt;sup&gt;2&lt;/sup&gt;/s in the soft (0.2-2keV) and hard (2-12 keV) X-ray band, respectively. The energy bands used in the 4XMM-DR14 processing were the same as for the 3XMM catalog. The following are the basic energy bands: &lt;pre&gt; 1 = 0.2 - 0.5 keV 2 = 0.5 - 1.0 keV 3 = 1.0 - 2.0 keV 4 = 2.0 - 4.5 keV 5 = 4.5 - 12.0 keV &lt;/pre&gt; while these are the broad energy bands: &lt;pre&gt; 6 = 0.2 - 2.0 keV soft band, no images made 7 = 2.0 - 12.0 keV hard band, no images made 8 = 0.2 - 12.0 keV total band 9 = 0.5 - 4.5 keV XID band &lt;/pre&gt; This database table was last updated by the HEASARC in July 2024. It contains the 4XMM-DR14 catalog, released by ESA on 2024-07-09 and obtained from the XMM-Newton Survey Science Center Consortium (&lt;a href="http://xmmssc.irap.omp.eu/Catalogue/4XMM-DR14/4XMM_DR14.html"&gt;http://xmmssc.irap.omp.eu/Catalogue/4XMM-DR14/4XMM_DR14.html&lt;/a&gt;).

Description:
X-ray sources at intermediate fluxes (a few x10^-14^erg/cm^2^/s) with a sky density of ~100deg^-2^ are responsible for a significant fraction of the cosmic X-ray background at various energies below 10keV. The aim of this paper is to provide an unbiased and quantitative description of the X-ray source population at these fluxes and in various X-ray energy bands. We present the XMM-Newton Medium sensitivity Survey (XMS), including a total of 318 X-ray sources found among the serendipitous content of 25 XMM-Newton target fields. The XMS comprises four largely overlapping source samples selected at soft (0.5-2keV), intermediate (0.5-4.5keV), hard (2-10keV) and ultra-hard (4.5-7.5keV) bands, the first three of them being flux-limited.
