Three dimensional structure in field 349 of the southern sky survey - I. Redshifts for a magnitude-limited sample of galaxies from slit spectra

Redshifts are presented for a magnitude-limited sample (bsub(J)<=16.5) of 107 galaxies detected from scans with the COSMOS machine in the central 29 square degrees of the ESO/ SERC southern sky survey field 349. Spectra at a dispersion of approx., 210 A mm-1 were obtained with the 1.9-m telescope of the South African Astronomical Observatory, using the Image-tube Spectrograph and Reticon Photon Counting System. Both cross-correlation techniques against filtered templates and direct measures of emission lines (if present) were used to obtain radial velocities to an accuracy of approx., 75 km s-1. (author)
