NED Abstract

Copyright by Royal Astronomical Society. 1998MNRAS.294..147M UBVRI photometry of the Durham-AAT redshift survey N. Metcalfe, A. Ratcliffe, T. Shanks and R. Fong Accepted 1997 September 29. Received 1996 August 19 ABSTRACT Using the PDS microdensitometer at the Royal Greenwich Observatory, we have acquired U, B, V, R and I surface photometry from UK Schmidt photographic plates for all the galaxies with measured redshifts in the Durham-AAT redshift survey. By comparison with CCD photometry we show that such precision photographic photometry of galaxies off IIIa emulsions is capable of an accuracy as good as a few hundredths of a magnitude. We discuss the colour-related properties of these galaxies, and derive luminosity functions in each waveband. We show that when divided by colour, the faint-end slope of the luminosity function of the bluer galaxies is significantly steeper than that for the redder ones. Key words: galaxies: fundamental parameters - galaxies: luminosity function, mass function - galaxies: photometry.
