Radial velocities
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.
