The significance of the observed coincidences was evaluated through Monte Carlo simulations of synthetic sources following a well-tested protocol. We found 3320 coincident radio/X-ray sources with a high statistical significance characterized by the sum of error-weighted coordinate differences. For 997 of them, 2MASS counterparts were found. The percentage of chance coincidences is less than 1%. X-ray hardness ratios of well-known populations of objects were used to provide a crude representation of their X-ray spectrum and to make a preliminary diagnosis of the possible nature of unidentified X-ray sources. The results support the fact that the X-ray sky is largely dominated by Active Galactic Nuclei at high galactic latitudes (|b|>=10deg). At low galactic latitudes (|b|<=10deg) most of unidentified X-ray sources (~94%) lie at |b|>=2deg. This result suggests that most of the unidentified sources found toward the Milky Way plane are galactic objects. Well-known and unidentified sources were classified in different tables with their corresponding radio/infrared and X-ray properties. These tables are intended as a useful tool for researchers interested in particular identifications. 2011Ap&SS.331...53C https://cdsarc.cds.unistra.fr/viz-bin/cat/V/138 Catalog Research IsServedBy TAP VizieR generic service IsServedBy Conesearch service https://cds.unistra.fr/vizier-org/licences_vizier.html https://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=V/138 https://vizier.iucaa.in/viz-bin/VizieR-2?-source=V/138 http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=V/138 https://vizier.cds.unistra.fr/viz-bin/votable?-source=V/138 https://vizier.iucaa.in/viz-bin/votable?-source=V/138 http://vizieridia.saao.ac.za/viz-bin/votable?-source=V/138 GET text/xml+votable https://tapvizier.cds.unistra.fr/TAPVizieR/tap Cone search capability for table V/138/catalog (X-ray and radio parameters of XMM-Newton source cross-matched radio sources from NVSS, MGPS2 and SUMSS) https://vizier.cds.unistra.fr/viz-bin/conesearch/V/138/catalog? https://vizier.iucaa.in/viz-bin/conesearch/V/138/catalog? http://vizieridia.saao.ac.za/viz-bin/conesearch/V/138/catalog?
