cds-question@unistra.fropen-star-clusterspre-main-sequence-starsinfrared-photometryWe use the results of a new multiepoch, multiwavelength, near-infrared census of the Trapezium cluster in Orion to construct and analyze the structure of its infrared (K-band) luminosity function. Specifically, we employ an improved set of model luminosity functions to derive this cluster's underlying initial mass function (IMF) across the entire range of mass from OB stars to substellar objects down to near the deuterium-burning limit. The observations were performed at FLWO (Fred Lawrence Whipple Observatory, Smithsonian Astrophysical Observatory), and ESO-NTT (European Southern Observatory, New Technology Telescope), between Dec. 1997 and Marche 2000 (see the "Table 5" section below)2002ApJ...573..366Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/573/366CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/2mass : The 2MASS database (IPAC/UMass, 2000)Table 5: Summary of Near-Infrared ObservationsNotes: FLWO: Fred Lawrence Whipple Observatory, Smithsonian AstrophysicalNTT: New Technology Telescope, European Southern Observatoryhttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/573/366https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/573/366http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/573/366https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/573/366https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/573/366http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/573/366GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/573/366/table6 (FLWO-NTT Near-Infrared Catalog)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/573/366/table6?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/573/366/table6?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/573/366/table6?GETtext/xml+votable180.050000true83.8435417-5.43636110.0055555555555555566/21439https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/573/366?format=asciiInfrareddefaultJ/ApJ/573/366/table6FLWO-NTT Near-Infrared CatalogrecnoRecord number assigned by the VizieR team.
