In this sample, no evidence is found for any extraneous, kinematically distinct population over the expected LMC and Galactic components. We discuss the significance of this finding for the LMC self-lensing models. The sample was randomly selected from three APM photographic plates with 16<=R<=18mag and -1.0<=Bj-R<=2.5mag. The fields were centered on previous microlensing events. The 1200V grating was used with 1.1{AA} per pixel resolution over 4625-5765{AA}. The zero point of the velocity of LMC K-type stars is set by cross-correlating with a K-type standard star. For sample stars of other spectral type we assume no systematic change of the peak of velocity distribution with spectral type.2003MNRAS.339..701Zhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/339/701CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/339/701https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/339/701http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/339/701https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/339/701https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/339/701http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/339/701GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/339/701/vhlmc (Kinematics and photometry for 1347 LMC stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/339/701/vhlmc?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/339/701/vhlmc?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/339/701/vhlmc?GETtext/xml+votable180.050000true79.844583-69.0372220.0055555555555555565/8263 8269 8274 6/33047 33051 33090-33091 33100-33102 33120-33121https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/339/701?format=asciiOpticalInfrareddefaultJ/MNRAS/339/701/vhlmcKinematics and photometry for 1347 LMC starsrecnoRecord number assigned by the VizieR team.
