cds-question@unistra.frmagellanic-cloudssurveysastronomical-object-identificationWe present the classification of 197 point sources observed with the Infrared Spectrograph in the SAGE-Spec Legacy programme on the Spitzer Space Telescope. We introduce a decision-tree method of object classification based on infrared spectral features, continuum and spectral energy distribution shape, bolometric luminosity, cluster membership and variability information, which is used to classify the SAGE-Spec sample of point sources. The decision tree has a broad application to mid-infrared spectroscopic surveys, where supporting photometry and variability information are available. We use these classifications to make deductions about the stellar populations of the Large Magellanic Cloud and the success of photometric classification methods. We find 90 asymptotic giant branch (AGB) stars, 29 young stellar objects, 23 post-AGB objects, 19 red supergiants, eight stellar photospheres, seven background galaxies, seven planetary nebulae, two HII regions and 12 other objects, seven of which remain unclassified.2011MNRAS.411.1597Whttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/411/1597CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/247 : Variable Stars in the Large Magellanic Clouds (MACHO, 2001)J/AJ/132/2268 : SAGE calibration stars (Meixner+, 2006)J/AJ/136/1242 : LMC long-period variables from MACHO (Fraser+, 2008)J/AcA/58/293 : Type-II and anomalous Cepheids in LMC (Soszynski+, 2008)J/AcA/59/239 : VI light curves of LMC long-period variables (Soszynski+, 2009)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/411/1597https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/411/1597http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/411/1597https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/411/1597https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/411/1597http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/411/1597GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/411/1597/table3 (Classification of point sources targeted in IRS staring mode as part of the SAGE-Spec program)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/411/1597/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/411/1597/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/411/1597/table3?GETtext/xml+votable180.050000true69.338125-70.57904720.0055555555555555564/2068 5/8263 8269 8280-8281 6/33043 33046-33047 33049 33051 33073 33080 33085 33104 33106-33107 33110 33112-33113 33115-33116 33132 33137-33138 37538https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/411/1597?format=asciiOpticaldefaultJ/MNRAS/411/1597/table3Classification of point sources targeted in IRS staring mode as part of the SAGE-Spec programNameName (1)meta.id;meta.maincharrecnoRecord number assigned by the VizieR team.
