Description:
Accurate positions and radial velocities are determined from 32 objective-
prism plates for two areas. Each field is observed twice with opposite
dispersion, allowing adjustment of coordinates for spectra not at the
plate centers. From the adjusted coordinates and plate overlap, positions
are determined with average mean errors: 0.0135 s in RA and 0.177 arcsec in
Dec for Area I (near the South Galactic Pole); 0.0315 s in RA, 0.144 arcsec
in Dec for Area II (near the galactic plane). Observations were taken by
J.D. MacConnell and G. Araya with a six degree prism on the Curtis Schmidt
telescope at Cerro Tololo.
