Abstract:
    The photometry data base of the second phase of the OGLE microlensing
    experiment, OGLE-II, is a rich source of information about the
    kinematics and structure of the Galaxy. In this work, we use the
    OGLE-II proper motion catalogue to identify candidate stars which have
    high proper motions. 521 stars with proper motion µ>50mas/yr
    in the OGLE-II proper motion catalogue were cross-identified with
    stars in the MACHO high proper motion catalogue, and the DEep
    Near-Infrared Survey and Two-Micron All-Sky Survey infrared photometry
    catalogues. Photometric distances were computed for stars with colours
    consistent with G/K- and M-type stars. Six stars were newly identified
    as possible nearby (<50pc) M dwarfs.

Note (2): The distance estimate, d, is determined using the theoretical

     Error values are derived from random photometric errors, statistical
     colour-luminosity scatter and systematic offset of the theoretical
     luminosity model
