Acknowledgements

We are grateful to the Australia Telescope Time Allocation Committee for granting us all the observing time necessary to complete this project. Part of this work was supported by the award of a UNSW Vice-Chancellor's Postdoctoral Fellowship to SDR. This research has made use of the NASA/IPAC Extragalactic Database (NED) which is operated by the Jet Propulsion Laboratory, California Institute of Technology, under contract with the National Aeronautics and Space Administration. The Digitized Sky Surveys were produced at the Space Telescope Science Institute under U.S. Government grant NAG W-2166. The images of these surveys are based on photographic data obtained using the Oschin Schmidt Telescope on Palomar Mountain and the UK Schmidt Telescope. The plates were processed into the present compressed digital form with the permission of those institutions.
