Digital Objective Prism Spectroscopy and Astrometry: Quantitative Methods and Application to High-Velocity Stars
We describe methods for extracting quantitative spectra and astrometricpositions from objective prism plates. In particular, we have studied7161 stars in eight fields along the south Galactic meridian using the6^deg+4^deg objective prisms on the Curtis Schmidt telescope at CerroTololo Inter-American Observatory. In this paper we concentrate ontechniques for deriving radial velocities and astrometric positions fromopposed dispersion plate pairs. For our data the typical accuracy inradial velocity is ~8 km s^-1. A catalog of 108 stars with high radialvelocities is presented, which is complete (and unbiased in eitherkinematics or metallicity) to a limiting B magnitude of 12.5 in theeight fields studied. Only two of this sample of 108 stars havepreviously reported radial velocities.

SANTIAGO 91, a right ascension catalogue of 3387 stars (equinox J2000).
The positions in right ascension of 3387 stars belonging to the Santiago67 Catalogue, observed with the Repsold Meridian Circle at Cerro Calan,National Astronomical Observatory, during the period 1989 to 1994, aregiven. The average mean square error of a position, for the wholeCatalogue, is +/-0.009 s. The mean epoch of the catalogue is 1991.84.

A kinematic and abundance survey at the galactic poles
The DDO intermediate band system is used to obtain detailed informationabout abundance gradients and velocity dispersions in the galaxy, withan emphasis on the properties of halo stars in the range of from 1 to 5kpc. The DDO abundance index is calibrated agianst (Fe/H) for metal-poorstars, with a resulting gradient of about -0.2 per kpc. However, whenthe sample is divided into two subsamples with (Fe/H) less than -0.5 andequal to or greater than -0.5, the gradients are -0.14 and 0.00,respectively. DDO observations of about 1000 stars, mostly G5-K5 giants,show that the velocity dispersion increases both with decrease inmetallicity and increase in z distance. The abundances found for high-zstars are similar to the A-star results of Rodgers (1971) in that abouthalf the K giants above 1 kpc appear to have solar abundances.

The K-giant population at the South Galactic Pole
CN anomalies and distances from the galactic plane have been derivedthrough DDO photometry for 171 late-type giant and subgiant stars nearthe South Galactic Pole. The previously found trend of the difference inCN concentration with distance (approximately equal to 0.09/kpc) holdsto approximately 2 kpc, but at greater distances from the plane theslope becomes approximately zero. The giants beyond 2 kpc are ofessentially normal composition or only slightly underabundant in heavierelements.
