cds-question@unistra.frsurveysx-ray-sourcesWe present a catalog of sources detected by the Mikhail Pavlinsky ART-XC telescope onboard the SRG space observatory during the observations of the Galactic plane region near a longitude l~20 deg (L20 field) in October 2019. The L20 field was observed four times in the scanning mode, which provided a uniform coverage of the sky region with a total area of ~24 sq. deg. with a median sensitivity of 8*10^-13^erg/s/cm^2^ (at 50% detection completeness) in the 4-12keV energy band. As a result, we have detected 29 X-ray sources at a statistically significant level, 11 of which have not been detected previously by other X-ray observatories. Preliminary estimates show that four of them can presumably be extragalactic in nature. We also show that the source SRGA J183220.1-103508 (CXOGSG J183220.8-103510) is most likely a galaxy cluster containing a bright radio galaxy at redshift z~0.121.2023PAZh...49..735Khttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/PAZh/49/735CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/MNRAS/529/941 : ART-XC Galactic bulge survey point sources cat.J/A+A/661/A38 : SRG/ART-XC 1st year all-sky X-ray survey (Pavlinsky+, 2022)https://www.srg.cosmos.ru : ART-XC cataloghttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/PAZh/49/735https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/PAZh/49/735http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/PAZh/49/735https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/PAZh/49/735https://vizier.iucaa.in/viz-bin/votable?-source=J/PAZh/49/735http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/PAZh/49/735GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/PAZh/49/735/table2 (SRG/ART-XC L20-field X-ray catalog)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/PAZh/49/735/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/PAZh/49/735/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/PAZh/49/735/table2?GETtext/xml+votable180.050000true274.5229-10.39570.0055555555555555566/29165 29506-29510 29513 29515 29517 29519-29520 29522-29523 29526 29528-29530 29540-29541 29552https://cdsarc.cds.unistra.fr/viz-bin/moc/J/PAZh/49/735?format=asciiX-raydefaultJ/PAZh/49/735/table2SRG/ART-XC L20-field X-ray catalogID[1/29] Source IDmeta.idintrecnoRecord number assigned by the VizieR team.
