cds-question@unistra.fropen-star-clustersphotometryproper-motionsradial-velocityline-intensitiesWith an apparent cluster diameter of 1.5deg and an age of ~4Myr, Trumpler 37 is an ideal target for photometric monitoring of young stars as well as for the search of planetary transits, eclipsing binaries and other sources of variability. The YETI consortium has monitored Trumpler 37 throughout 2010 and 2011 to obtain a comprehensive view of variable phenomena in this region. In this first paper we present the cluster properties and membership determination as derived from an extensive investigation of the literature. We also compared the coordinate list to some YETI images. For 1872 stars we found literature data. Among them 774 have high probability of being member and 125 a medium probability. Based on infrared data we re-calculate a cluster extinction of 0.9-1.2mag. We can confirm the age and distance to be 3-5Myr and ~870pc. Stellar masses are determined from theoretical models and the mass function is fitted with a power-law index of {alpha}=1.90 (0.1-0.4M_{sun}_) and {alpha}=1.12 (1-10M_{sun}_).2013AN....334..673Ehttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AN/334/673CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AJ/128/805 : Low-mass stars in Cepheus OB2 region (Sicilia-Aguilar+ 2004)J/AJ/130/188 : Young stars in Trumpler 37 & NGC7160 (Sicilia-Aguilar+, 2005)J/ApJ/638/897 : IR photometry in Trumpler 37 & NGC7160 (Sicilia-Aguilar+, 2006)J/AJ/132/2135 : High-resolution spectroscopy in Tr 37 (Sicilia-Aguilar+, 2006)J/MNRAS/426/2917 : X-rays sources in Trumpler 37 (Getman+, 2012)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AN/334/673https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AN/334/673http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AN/334/673https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AN/334/673https://vizier.iucaa.in/viz-bin/votable?-source=J/AN/334/673http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AN/334/673GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AN/334/673/stars (Literature data and membership estimations for Trumpler 37 stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AN/334/673/stars?https://vizier.iucaa.in/viz-bin/conesearch/J/AN/334/673/stars?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AN/334/673/stars?GETtext/xml+votable180.050000true324.194041757.19038890.0055555555555555565/3869 3871 6/15454-15455 15473-15475 15481 15483 15558 15572 15630 15648 15650 15652 156568.650015785639275e-20 6.118840631666147e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AN/334/673?format=asciiOpticaldefaultJ/AN/334/673/starsLiterature data and membership estimations for Trumpler 37 starsSpTypeSpectral typesrc.spTypecharrecnoRecord number assigned by the VizieR team.
