Improved Astrometry and Photometry for the Luyten Catalog. II. Faint Stars and the Revised Catalog
We complete construction of a catalog containing improved astrometry andnew optical/infrared photometry for the vast majority of NLTT starslying in the overlap of regions covered by POSS I and by the secondincremental Two Micron All Sky Survey (2MASS) release, approximately 44%of the sky. The epoch 2000 positions are typically accurate to 130 mas,the proper motions to 5.5 mas yr-1, and the V-J colors to0.25 mag. Relative proper motions of binary components are measured to 3mas yr-1. The false-identification rate is ~1% for11<~V<~18 and substantially less at brighter magnitudes. Theseimprovements permit the construction of a reduced proper-motion diagramthat, for the first time, allows one to classify NLTT stars intomain-sequence (MS) stars, subdwarfs (SDs), and white dwarfs (WDs). We inturn use this diagram to analyze the properties of both our catalog andthe NLTT catalog on which it is based. In sharp contrast to popularbelief, we find that NLTT incompleteness in the plane is almostcompletely concentrated in MS stars, and that SDs and WDs are detectedalmost uniformly over the sky δ>-33deg. Our catalogwill therefore provide a powerful tool to probe these populationsstatistically, as well as to reliably identify individual SDs and WDs.

G. P. Kuiper's spectral classifications of proper-motion stars
Spectral classifications are listed for over 3200 stars, mainly of largeproper motion, observed and classified by Kuiper during the years1937-1944 at the Yerkes and McDonald Observatories. While Kuiper himselfpublished many of his types, and while improved classifications are nowavailable for many of these stars, much of value remains. For many ofthe objects, no other spectral data exist.

Radial velocities for selected southern high-velocity stars
Radial velocities for more than 100 southern high-velocity stars fromthe catalog of Buscombe and Morris (1958) are obtained by using bothdirect and image-tube UBV spectroscopy. The observational procedure anddata reduction technique are described. Two stars on the observing listare found to have enormous radial velocities and very weak metalliclines: LTT 2571, with a radial velocity of +346 km/s, and LTT 2625, witha radial velocity of +301 km/s. Other unusual objects discovered includeLTT 2813, which reaches over 100 kpc from the galactic center with anorbital eccentricity of 0.85, and LTT 8376, which travels about thegalactic center in a retrograde orbit with large energy. It is notedthat LTT 2813 and LTT 8376, as well as nearly all other objects on thelist, display normal or nearly normal metallic lines.
