Catalog Description:
The LSPM catalog is a comprehensive list of 61,977 stars north of the
J2000 celestial equator, which have proper motions larger than 0.15
seconds of arc per year. The catalog has been generated primarily as a
result of our systematic search for high proper motion stars in the Digitized
Sky Surveys using our SUPERBLINK software. At brighter magnitudes,
the catalog incorporates stars and data from the Tycho-2 Catalogue and
also, to a lesser extent, from the All-sky Compiled Catalogue of 2.5 million
stars. The LSPM catalog expands considerably over the old Luyten (LHS,
NLTT) catalogs, superseding them for northern declinations. Positions
are given with an accuracy <100 mas at the 2000.0 epoch, and absolute
proper motions are given with an accuracy of <8 mas/yr. Whenever
available, we also give optical $B_T$ and V$_T$ magnitudes (from
TYCHO-2, ASCC-2.5), photographic BJ RF and IN magnitudes (from
USNO-B1 catalog) and infrared J H and Ks magnitudes (from 2MASS).
We also provide an estimated V magnitude and V-J color for every star
in the catalog, useful for initial classification of the stars. The catalog is
estimated to be over 99% complete at high Galactic latitudes (|b|>15),
and over 90% complete at low Galactic latitudes (|b|>15), down to a
magnitude V=19.0, with a limiting magnitude V=21.0. All the northern stars
listed in the LHS and NLTT catalogs have been re-identified, and their
positions, proper motions and magnitudes re-evaluated. The catalog also
lists a large number of completely new objects, which promise to expand
very significantly the census of red dwarfs, subdwarfs, and white dwarfs in
the vicinity of the Sun.
