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
luminosity model of Baraffe et al. (1998, Cat. J/A+A/337/403).
Error values are derived from random photometric errors, statistical
colour-luminosity scatter and systematic offset of the theoretical
luminosity model
