cds-question@unistra.frstellar-associationslate-type-starspre-main-sequence-starsphotometryWe present the results of a proper motion study aiming at providing further evidence on the origin of the proposed stellar members of the Chamaeleon I and II clouds and to identify interlopers from the foreground young clusters {epsilon} Cha and {eta} Cha. We compiled lists of spectroscopically confirmed members of the four associations, and of background objects in the same line of sight. Using Virtual Observatory tools, we cross-matched these lists with the UCAC3 (Cat. I/315) catalogue to get proper motions for the objects. In the vector point diagram, we identified the different moving groups, and used this information to study the membership of proposed candidate members of the associations from the literature. For those objects with available radial velocities, we computed their Galactic space velocities. We compiled photometry from public data archives and from the literature for the Cha I and II objects. We looked for correlations between the properties of the objects and their proper motions.2013A&A...551A..46Lhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/551/A46CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/denis : The DENIS database (DENIS Consortium, 2005)II/311 : WISE All-Sky Data Release (Cutri+ 2012)II/297 : AKARI/IRC mid-IR all-sky Survey (ISAS/JAXA, 2010)I/315 : UCAC3 Catalogue (Zacharias+ 2009)II/246 : 2MASS All-Sky Catalog of Point Sources (Cutri+ 2003)I/259 : The Tycho-2 Catalogue (Hog+ 2000)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/551/A46https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/551/A46http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/551/A46https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/551/A46https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/551/A46http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/551/A46GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/551/A46/table1 (95 confirmed members of Chamaeleon I and II with UCAC3 proper motions (excluding wrong measurements and interlopers))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/551/A46/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/551/A46/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/551/A46/table1?GETtext/xml+votable180.050000true161.6579272-77.60099610.005555555555555556Cone search capability for table J/A+A/551/A46/table2 (Kinematic members of the foreground {epsilon} and {eta} Chamaeleontis clusters (excluding wrong measurements and interlopers))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/551/A46/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/551/A46/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/551/A46/table2?GETtext/xml+votable180.050000true164.4557314-69.23331940.005555555555555556Cone search capability for table J/A+A/551/A46/table3 (Background objects)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/551/A46/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/551/A46/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/551/A46/table3?GETtext/xml+votable180.050000true161.3660467-77.25933720.005555555555555556Cone search capability for table J/A+A/551/A46/table5 (Hipparcos and Tycho proper motions and Hipparcos parallaxes for Chamaeleon stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/551/A46/table5?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/551/A46/table5?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/551/A46/table5?GETtext/xml+votable180.050000true161.6579272-77.60099610.005555555555555556Cone search capability for table J/A+A/551/A46/table7 (Kinematic properties of ROSAT stars not included in our initial member lists)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/551/A46/table7?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/551/A46/table7?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/551/A46/table7?GETtext/xml+votable180.050000true172.3026456-75.77400440.005555555555555556Cone search capability for table J/A+A/551/A46/table8 (UCAC3 proper motions for candidate members of the Chamaeleon dark clouds from the literature)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/551/A46/table8?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/551/A46/table8?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/551/A46/table8?GETtext/xml+votable180.050000true167.4435581-76.48266360.005555555555555556Cone search capability for table J/A+A/551/A46/table9 (Space velocities for members and candidate members of the Chamaeleon associations)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/551/A46/table9?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/551/A46/table9?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/551/A46/table9?GETtext/xml+votable180.050000true163.999175-77.41114580.0055555555555555565/9239 9280 10282-10283 6/36888 36901 36914 36928 36938 36943 36946 36948 36950 36953-36955 36960-36961 36963 36969 36978 36983 37012-37013 37056 37060 37065 37125 37128-37129 37131 37134 37173 41120 41126-41127 41139 41472 41480-41481 41484 41505-41506 41526 41528 416007.952274030004205e-20 3.3785437584409506e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/551/A46?format=asciidefaultJ/A+A/551/A46/table195 confirmed members of Chamaeleon I and II with UCAC3 proper motions (excluding wrong measurements and interlopers)recnoRecord number assigned by the VizieR team.
