The survey was carried out with the wide-field grism spectrograph (WFGS) on the University of Hawaii 2.2m telescope on Mauna Kea. X-ray observations made with the European Photon Imaging Camera (EPIC) on board the European Space Agency's XMM-Newton satellite observatory will be discussed in a subsequent paper. Optical (BVR_C_I_C_) photometry was obtained for selected fields to supplement similar data from the literature. Spectra covering the 6000-8000{AA} region at a resolution of R~3000 (adequate for the determination of Li I {lambda}6708 line strengths) were obtained for 150 H{alpha} and X-ray emission sources with the Gemini Multi-Object Spectrograph (GMOS).2005AJ....129..829Dhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/129/829CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AJ/127/2228 : VRI photometry of PMS stars in NGC 2264 OB (Makidon+, 2004)J/A+A/417/557 : Rotation + variability of PMS Stars in NGC 2264 (Lamm, 2004)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/129/829https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/129/829http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/129/829https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/129/829https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/129/829http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/129/829GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/129/829/table1 (H{alpha} emission stars in NGC 2264)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/129/829/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/129/829/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/129/829/table1?GETtext/xml+votable180.050000true100.02295839.37372220.0055555555555555566/23636 23637 236391.5062136169708525e-19 1.7003137259100215e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/129/829?format=asciiOpticaldefaultJ/AJ/129/829/table1H{alpha} emission stars in NGC 2264recnoRecord number assigned by the VizieR team.
