Abstract:
    We present the first part of a new catalog of variable stars
    (OIII-CVS) compiled from the data collected in the course of the third
    phase of the Optical Gravitational Lensing Experiment (OGLE-III). In
    this paper we describe the catalog of 3361 classical Cepheids detected
    in the ∼40 square degrees area in the Large Magellanic Cloud. The
    sample consists of 1848 fundamental-mode (F), 1228 first-overtone
    (1O), 14 second-overtone (2O), 61 double-mode F/1O, 203 double-mode
    1O/2O, 2 double-mode 1O/3O, and 5 triple-mode classical Cepheids. This
    sample is supplemented by the list of 23 ultra-low amplitude variable
    stars which may be Cepheids entering or exiting instability strip
Description:
    The catalog data include VI high-quality photometry collected since
    2001, and for some stars supplemented by the OGLE-II photometry
    obtained between 1997 and 2000. We provide basic parameters of the
    stars: coordinates, periods, mean magnitudes, amplitudes and
    parameters of the Fourier light curve decompositions. Our sample of
    Cepheids is cross-identified with previously published catalogs of
    these variables in the LMC. Individual objects of particular interest
    are discussed, including single-mode second-overtone Cepheids,
    multiperiodic pulsators with unusual period ratios or Cepheids in
    eclipsing binary systems.
