III/172     Radial Velocities from Objective Prism Plates (Stock 1992)

Radial Velocities from Objective Prism Plates

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.
