2001AJ....122..714B V- AND R-BAND GALAXY LUMINOSITY FUNCTIONS AND LOW SURFACE BRIGHTNESS GALAXIES IN THE CENTURY SURVEY WARREN R. BROWN, MARGARET J. GELLER, DANIEL G. FABRICANT, AND MICHAEL J. KURTZ Harvard-Smithsonian Center for Astrophysics, 60 Garden Street, Cambridge, MA 02138; wbrown@cfa.harvard.edu, mgeller@cfa.harvard.edu, dfabricant@cfa.harvard.edu, mkurtz@cfa.harvard.ed Received 2001 March 8; accepted 2001 May 8 ABSTRACT We use 64 deg^2^ of deep V and R CCD images to measure the local V- and R-band luminosity functions of galaxies. The V_0_ < 16.7 and R_0_ < 16.2 redshift samples contain 1255 and 1251 galaxies and are 98.1% and 98.2% complete, respectively. We apply k-corrections before the magnitude selection so that the completeness is to the same depth for all spectral types. The V and R faint-end slopes are surprisingly identical: {alpha} = -1.07 +/- 0.09. Representative Schechter function parameters for H_0_ = 100 are: M_R_^*^ = -20.88 +/- 0.09, {phi}_R_^*^ = 0.016 +/- 0.003 Mpc^-3^ and M_V_^*^ = -20.23 +/- 0.09, {phi}_V_^*^ = 0.020 +/- 0.003 Mpc^-3^. The V and R local luminosity densities, j_R_ = (1.9 +/- 0.6) x 10^8^ L_sun_ and j_V_ = (2.2 +/- 0.7) x 10^8^ L_sun_, are in essential agreement with the recent 2 Degree Field Galaxy Redshift Survey and Sloan Digital Sky Survey determinations. All low surface brightness (LSB) galaxies fall in the large-scale structure delineated by high surface brightness galaxies. The properties and surface number density of our LSB galaxies are consistent with the LSB galaxy catalog of O'Neil, Bothun & Cornell, suggesting that our samples are complete for LSB galaxies to the magnitude limits. We measure colors, surface brightnesses, and luminosities for our samples, and find strong correlations among these galaxy properties. The color-surface brightness relation is (V - R)_0_ = (-0.11 +/- 0.05) {mu}_R, 0_ + (2.6 +/- 0.9). Key words: cosmology: observations - galaxies: fundamental parameters - galaxies: luminosity function, mass function - galaxies: photometry - large-scale structure of universe
