cds-question@unistra.frstellar-associationspre-main-sequence-starsyoung-stellar-objectsvariable-starsinfrared-photometrysurveysWe present the results of a near-infrared time-series photometry study in the field of Cygnus OB2 association (RA~20.55h, DE~41.2{deg}). Observations were carried out in the JHK bands at the WFCAM/UKIRT telescope over 112 observed nights. We investigated the occurrence of periodicity in the time-series and we found reliable periods for 894 candidate members.2017A&A...603A.106Rhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/603/A106CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJ/773/135 : Disk-bearing stars in Cygnus OB2 (Guarcello+, 2013)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/603/A106https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/603/A106http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/603/A106https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/603/A106https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/603/A106http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/603/A106GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/603/A106/table1 (Rotational periods for CygOB2 periodic candidate members)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/603/A106/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/603/A106/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/603/A106/table1?GETtext/xml+votable180.050000true308.0166741.238610.0055555555555555566/14670-14671 14692-146938.297946179207444e-20 1.6867587740958882e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/603/A106?format=asciiInfrareddefaultJ/A+A/603/A106/table1Rotational periods for CygOB2 periodic candidate membersAV?
