Scientific paper

In this paper, new redshifts are presented for 228 galaxies located south of declination -30 deg. The observations were made with a photon-counting Reticon detector on the Observatorio Nacional (ON) 60-in. telescope. The detector is identical to the one used at Mount Hopkins for the CfA Redshift Survey, and the redshifts were derived using the same data-analysis system. A preliminary comparison with published 21-cm redshifts indicates that the velocities have a zero-point offset of about -4 km/s, with a typical uncertainty of 40 km/s. The observations reported here are the initial results of the ON-CfA Redshift Survey currently being undertaken in the southern hemisphere.
