The luminosity function in the Petrosian r band bivariate with various galaxy parameters has been computed for Main Sample galaxies in the SDSS Data Release 4, with the addition of data from the New York Value Added Galaxy Catalog (VAGC), the Pittsburgh-CMU Value-Added Galaxy Catalog (VAC), the MPA-Garching catalog 'Physical properties for galaxies and active galactic nuclei', and the SDSS Japan Participation Group.
The parameters are eyeball Hubble type, Hubble type assigned by an artificial neural network, inverse concentration index, the Sersic index of the light profile, absolute effective surface brightness, reference frame colors u-g, g-r, r-i and i-z, absolute radius, eClass spectral type, stellar mass and galaxy environment.
We used the bivariate formulation of the stepwise maximum likelihood method of Efstathiou, Ellis and Peterson (1988), taking into account completeness in each bin. The magnitudes are extinction- and K-corrected, the latter using version 4.1.14 of Mike Blanton's K-correct code.
The final results are described in 'Bivariate Galaxy Luminosity Functions in the Sloan Digital Sky Survey', MNRAS 373 845, or astro-ph/0507547.
