Abstract:
    We present the results of a large spectroscopic survey of the LMC,
    consisting of more than 1300 radial velocities measured accurately
    with the 2dF instrument during three observing compaigns 1999-2002. 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 1.1Å per pixel resolution over 4625-5765Å. 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.

Description:
    Kinematics and photometry of 1347 stars in the LMC are given.
    For each star, the RA and DEC, the heliocentric radial velocity,
    the R magnitude and Bj-R color are given.
