  We present a V-J reduced proper motion (RPM) diagram for stars in the New
Luyten Two-Tenths (NLTT) catalog. In sharp contrast to the RPM diagram based on
the original NLTT data, this optical-infrared RPM diagram shows distinct tracks
for white dwarfs, subdwarfs, and main-sequence stars. It thereby permits the
identification of white-dwarf and subdwarf candidates that have a high
probability of being genuine.
