cds-question@unistra.fropen-star-clustersvariable-starsinfrared-photometryvisible-astronomyphotometrySince 2004, we have been engaged in a long-term observing programme to monitor young stellar objects (YSOs) in the Orion Nebula Cluster (ONC). We have collected about 2000 frames in V, R and I broad-band filters on more than 200 nights distributed over five consecutive observing seasons. The high-quality and time-extended photometric data give us an opportunity to address various phenomena associated with young stars.2009MNRAS.400..603Phttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/400/603CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AJ/117/2941 : Rotation periods of Orion PMS stars (Stassun+, 1999)J/A+A/396/513 : Stellar Rotation in the Orion Nebula Cluster (Herbst+, 2002)J/ApJ/660/704 : Optical and X-ray variability of ONC PMS (Stassun+, 2007)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/400/603https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/400/603http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/400/603https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/400/603https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/400/603http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/400/603GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/400/603/table2 (The photometric data along with other relevant information of all 346 stars in our FoV)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/400/603/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/400/603/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/400/603/table2?GETtext/xml+votable180.050000true83.82692083-5.401952780.0055555555555555566/21438-214391.398457827073138e-19 2.6706780932288093e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/400/603?format=asciiOpticalInfrareddefaultJ/MNRAS/400/603/table2The photometric data along with other relevant information of all 346 stars in our FoVSkySky conditions flag (G1)meta.codecharDEJ2000Declination (J2000)pos.eq.dec;meta.mainrecnoRecord number assigned by the VizieR team.
