Laurent.michel@astro.unistra.fr (33-0) 368 852 437 4XMM Catalogue The 4XMM-DR14 catalogue contains source detections drawn from 13864 XMM-Newton EPIC observations, covering an energy interval from 0.2 keV to 12 keV. These observations were made between 2000 February 3 and 2023 December 31 and all datasets were publicly available by 2023 December 31, but not all public observations are included i n this catalogue. The median flux in the total photon energy band (0.2 - 12 keV) of the catalogue detections is ~ 2.2 × 10-14 erg cm-2 s-1; in the soft energy band (0.2 - 2 keV) the median flux is ~ 5.2 × 10-15, and in the hard band (2 - 12 keV) it is ~ 1.2 × 10-14. About 23% of the sources have total fluxes below 1 × 10-14 erg cm-2 s-1. About a tenth of the observations have features that may cause spurious detections (mainly the wings of bright sources and large extended emission), and it is strongly recommended to use a filter (both per source, based on the summary flag column, and per observation, based on the observation class column). http://xmmssc.irap.omp.eu/ https://xcatdb.unistra.fr/xtapdb ADQL 2.0 ADQL 2.0
