1992ApJ...390..338L THE STROMLO-APM REDSHIFT SURVEY. I. THE LUMINOSITY FUNCTION AND SPACE DENSITY OF GALAXIES J. LOVEDAY AND B. A. PETERSON Mount Stromlo and Siding Spring Observatories, Private Bag, Weston Creek Post Office, ACT 2611, Australia AND G. EFSTATHIOU AND S. J. MADDOX Department of Physics, Keble Road, Oxford, OX1 3RH, England, UK Received 1991 August 14; accepted 1991 November 8 ABSTRACT We present the first results from a new redshift survey of southern galaxies. The survey is essentially complete to a magnitude limit of b_J_ = 17.15 and consists of 1769 galaxies sampled randomly at a rate of 1 in 20 from the APM galaxy catalogs. Our survey samples a volume ~30 times larger than the 14.5 mag CfA Redshift Survey and so can provide an accurate determination of the luminosity function and mean space density of galaxies. After correction for Malmquist bias, the luminosity function is well fitted over the magnitude range - 15 > M_bJ_ > - 22 by a Schechter function with parameters M^*^_bJ_ = - 19.50+/-0.13, {alpha} = - 0.97+/-0.15, and {phi}^*^ = (1.40+/-0.17) x 10^-2^ Mpc^-3^ for H_0_ = 100 kms^-1^ Mpc^-1^. We estimate the variation of galaxy density with redshift using a maximum-likelihood method. The absence of a large local void in our survey supports our previous conclusion that the galaxy population must evolve rapidly at relatively low redshifts (z ~ 0.1) to explain the observed number counts over the range 16 <~ b_J_ <~ 19.
