Abstract:
We present a catalog of high proper motion (HPM) stars detected in the
foreground of central parts of the Magellanic Clouds. The Catalog
contains 2161 objects in the 4.5 square degree area towards the LMC,
and 892 HPM stars in the 2.4 square degree area towards the SMC. The
Catalog is based on observations collected during four years of the
OGLE-II microlensing survey. The Difference Image Analysis (DIA) of
the images provided candidate HPM stars with proper motion as small as
4mas/yr. These appeared as pseudo-variables, and were all measured
astrometrically on all CCD images, providing typically about 400 data
points per star. The reference frame was defined by the majority of
background stars, most of them members of the Magellanic Clouds. The
reflex motion due to solar velocity with respect to the local
standards of rest is clearly seen. The largest proper motion in our
sample is 363mas/yr. Parallaxes were measured with errors smaller
than 20% for several stars.
