cds-question@unistra.frpre-main-sequence-starsx-ray-sourcesline-intensitiesWe present results of a study to investigate the spatial distribution of X-ray active young stellar objects near the Lupus star forming region (SFR). In this SFR, a recent study has led to the discovery of some 130 new weak-line T Tauri stars (WTTS) dispersed over a large area of some 230 square degrees. However, the true extent of the spatial distribution of these stars could not be determined in this study.1997A&A...326..211Whttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/326/211CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toIX/10 : ROSAT All-Sky Bright Source Catalogue (1RXS) (Voges+ 1996)IX/11 : ROSAT Source Catalog (Voges+ 1994)I/289 : UCAC2 Catalogue (Zacharias+ 2004)II/246 : 2MASS All-Sky Catalog of Point Sources (Cutri+ 2003)I/259 : The Tycho-2 Catalogue (Hog+ 2000)J/A+AS/123/329 : New weak-line T Tauri stars in Lupus (Krautter+ 1997)J/A+A/320/185 : T Tauri UBVRIcJHKL photometry (Wichmann+ 1997)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/326/211https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/326/211http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/326/211https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/326/211https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/326/211http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/326/211GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/326/211/table1 (WTTS identified with RASS X-ray sources within the region surveyed in this work.)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/326/211/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/326/211/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/326/211/table1?GETtext/xml+votable180.050000true212.707083-23.9244440.0055555555555555566/41943 41972-41973 41981 41983 42544 42628 42634-42635 42653 42662 42664 43356 44032 44034 44036 44039-44040 44050-44051 44059 44061-44063 44065 44069 44076 44081 44083 44104 44106 44136 44204 44583 44593 44745https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/326/211?format=asciiX-raydefaultJ/A+A/326/211/table1WTTS identified with RASS X-ray sources within the region surveyed in this work.UCAC2?
