IX/47 Enhanced 3XMM catalogue (3XMMe) (Rosen+, 2016) ================================================================================ ARCHES. The enhanced 3XMM catalogue (3XMMe). Rosen S. =2016yCat.9047....0R ================================================================================ ADC_Keywords: X-ray sources ; Surveys Mission_Name: XMM Abstract: The enhanced 3XMM catalogue (designated 3XMMe) is one of the core elements of the Arches project, representing the X-ray source basis for the cross-correlations with other multi-wavelength catalogues. The 3XMMe catalogue is a derivative of the latest increment of the 3XMM catalogue, i.e. 3XMM-DR5, that was publicly released in April 2015 (Rosen et al., 2016A&A...590A...1R, Cat. XI/46)), tailored for the purposes of the Arches project. The 3XMM-DR5 catalogue, available from the XMM-Newton Science Archive (http://xmm.esac.esa.int/xsa/), the XMM-Newton Survey Science Centre (SSC) (http://xmmssc.irap.omp.eu) and other sites listed on the SSC site, contains 565962 detections arising from 396910 unique sources drawn from 7781 XMM observations. These numbers include detections from 356 sub-pointings made in mosaic mode. Arches wed site : http://www.arches-fp7.eu . Description: The construction of the enhanced 3XMM catalogue involves 3 main elements: 1. The cleaning (ejection) of detections that are considered to be of lower scientific reliability or quality. 2. Application of criteria to identify detections that are considered potential candidates for the 3 main science themes (i.e. active galactic nuclei (AGN), clusters of galaxies and the galactic plane) of the Arches project. The constituent detections of unique sources on the sky are examined to decide which unique sources, overall, meet the criteria to be assigned to each science theme. 3. Addition of other information that augments the scientific value of the catalogue. The primary publicly released version of the catalogue is based on unique sources rather than separate detections. However, a detection-based catalogue is available.

(1): The hardness ratio is defined as (F2-F1)/(F2+F1) if F2 is the count rate in the harder band (the hardness ratio is therefore -1 for softest sources and +1 for hardest sources). The energy bands are: 1 = 0.2 - 0.5 keV (narrow band) 2 = 0.5 - 1.0 keV (narrow band) 3 = 1.0 - 2.0 keV (narrow band) 4 = 2.0 - 4.5 keV (narrow band) 5 = 4.5 - 12.0 keV (narrow band) 6 = 0.2 - 2.0 keV = soft broad band, no images made 7 = 2.0 - 12.0 keV = hard broad band, no images made 8 = 0.2 - 12.0 keV = total band 9 = 0.5 - 4.5 keV = XID band Note (2): defined as the maximum of the likelihoods of all detections of this source. Note (3): extent of the constituent detection with the largest likelihood among all detections of this source. Note (4): {chi}^2^ probability that the unique source as detected by any of the observations is constant, that is, the minimum value of the EPIC probabilities in each detection. Note (5): the summary flag of the source is derived from the EPIC flag, and is assigned the following values: 0 = good: none of the EPIC flags was set. 1 = source parameters may be affected: at least one of the EPIC warning flags was set, but no possible-spurious detection flag is set. 2 = possibly spurious source: at least one of the possible-spurious detection flags was set but not the manual flag 3 = source located in a area where spurious detection may occur. 4 = source located in a area where spurious detection may occur and is possibly spurious. Note (6): The fractional excess variance of the unique source. It is the value corresponding to the exposure and instrument that shows the lowest probability of being constant. Note (8): see http://irsa.ipac.caltech.edu/applications/DUST/. These values replace the original E(B-V) measures provided in 3XMMe v1.2 that were based on Schlegel, Finkbeiner & Davis, (1998ApJ...500..525S). Note (9): Hydrogen column density value based on the relation between NH and Av, i.e. Nh=1.79e21*Av (Predehl & Schmitt, 1995A&A...293..889P) where Av is derived from the above-mentioned EBMV_DUST value using Av=Rv*E(B-V) where Rv=3.1 (Schlafly & Finkbeiner, 2011ApJ...737..103S). These values replace the original E(B-V) measures provided in 3XMMe v1.2 that were based on Schlegel, Finkbeiner & Davis, (1998ApJ...500..525S). Note (10): Number of constituent detections in a unique source that pass the filtering criteria, expressed as a fraction of the total number of constituent detections making up the source. Note that these numbers all refer to the numbers of detections that survived the cleaning stage in the production of the enhanced 3XMM catalogue. Note (11): based on the work of Willingale et al. (2013MNRAS.431..394W), see http://www.swift.ac.uk/analysis/nhtot/docs.php. -------------------------------------------------------------------------------- History: From http://www.arches-fp7.eu/index.php/tools-data/downloads/enhanced-catalogue ================================================================================ (End) Patricia Vannier [CDS] 29-Apr-2016
