Abstract

A large observing program of a complete sample of 248 elliptical and SO galaxies has been completed. The sample comprises all such galaxies south of declination -32° to a limiting magnitude (BT) of 14.0. The observations include accurate radial velocity measurements (~30 km/s error), UBV aperture photometry and radio continuum flux densities at 2700 MHz (11 cm) and 5000 MHz (6 cm). A later analysis shows the sample to be 90% complete at BT = 13.8 and 80% complete at BT = 14.0.
