cds-question@unistra.frsurveysx-ray-sourcesactive-galactic-nucleigalaxy-clustersquasarsx-ray-binary-starsThe eROSITA X-ray telescope on board the Spectrum-Roentgen-Gamma (SRG) spacecraft observed the field of the UKIDSS Ultra-Deep Survey (UDS) in August-September 2019, during its flight to Sun-Earth L2 point. The resulting eROSITA UDS (or eUDS) survey was thus the first eROSITA X-ray imaging survey, which demonstrated the capability of the telescope to perform uniform observations of large sky areas. With a moderate single-camera exposure of 150ks, eUDS covered ~5deg^2^ with the limiting flux ranging between 4*10^-15^ and 5*10^-14^erg/cm^2^/s in the 0.3-2.3keV band. We present a catalogue of 647 sources detected at likelihood >10 (~4sigma) during the eUDS. The catalogue provides information on the source fluxes in the main energy band 0.3-2.3keV and forced photometry in a number of bands between 0.3 and 8keV. Using the deeper 4XMM-DR12 catalogue, we have identified 22 strongly variable objects that have brightened or faded by at least a factor of ten during the eROSITA observations compared to previous observations by XMM-Newton. We also provide a catalogue of 22 sources detected by eROSITA in the hard energy band of 2.3-5keV.2024MNRAS.528.1264Khttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/528/1264CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/661/A1 : The eFEDS X-ray catalogs (Brunner+, 2022)J/A+A/661/A38 : SRG/ART-XC 1st year all-sky X-ray survey (Pavlinsky+, 2022)https://www.srg.cosmos.ru/eUDS : eUDS cataloghttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/528/1264https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/528/1264http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/528/1264https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/528/1264https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/528/1264http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/528/1264GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/528/1264/tablea1 (eUDS X-ray catalog, converted from eUDS.fits)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/528/1264/tablea1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/528/1264/tablea1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/528/1264/tablea1?GETtext/xml+votable180.050000true33.51418806-4.265770.005555555555555556Cone search capability for table J/MNRAS/528/1264/tablea2 (eUDS forced photometry of 4XMM-DR12 sources, converted from eUDS_4XMM-DR12.fits)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/528/1264/tablea2?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/528/1264/tablea2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/528/1264/tablea2?GETtext/xml+votable180.050000true33.39758889-4.661806110.0055555555555555565/4422 6/17677 17679 17694 17701 17712-17713 17716https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/528/1264?format=asciiX-raydefaultJ/MNRAS/528/1264/tablea1eUDS X-ray catalog, converted from eUDS.fitsrecnoRecord number assigned by the VizieR team.
