cds-question@unistra.fractive-galactic-nucleiradio-sourcesx-ray-sourcesThe cross-correlation of a source list from the ROSAT All-Sky Survey with the Molonglo 408MHz survey (MRC) yields to a catalogue of 549 sources. The majority of the objects are quasars and radio galaxies with known optical counterparts; more than one third of the objects are optically unidentified.1994A&A...281..355Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/281/355CatalogResearchIsServedByTAP VizieR generic servicerelated-toVIII/16 : MRC (Molonglo Reference Catalog)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/281/355https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/281/355http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/281/355https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/281/355https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/281/355http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/281/355GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapX-rayRadiodefaultJ/A+A/281/355/table2MRC-ROSAT sources with identificationsrecnoRecord number assigned by the VizieR team.
