Abstract:
    We present a proper-motion catalogue of 5080236 stars in 49 Optical
    Gravitational Lensing Experiment II (OGLE-II) Galactic bulge (GB)
    fields, covering a range of -11{deg}<l<11{deg} and -6{deg}<b<3{deg},
    the total area close to 11deg^2^. The proper-motion measurements are
    based on 138-555 I-band images taken during four observing seasons:
    1997-2000. The catalogue stars are in the magnitude range 11<I<18mag.
    In particular, the catalogue includes red clump giants and red giants
    in the GB, and main-sequence stars in the Galactic disc. The proper
    motions up to pm=500mas/yr were measured with a mean accuracy of
    0.8-3.5mas/yr, depending on the brightness of a star. This catalogue
    may be useful for studying the kinematics of stars in the GB and the
    Galactic disc.

Description:
    We use the data collected during the second phase of the OGLE
    experiment, between 1997 and 2000. All observations were made with the
    1.3-m Warsaw telescope located at the Las Campanas Observatory, Chile,
    which is operated by the Carnegie Institution of Washington.
