In companion papers, theangular correlation function w(θ) and two-dimensional powerspectrum Cl of these galaxies are presented. Here we invertLimber{\textquoteright}s equation to extract the three-dimensional power spectrum fromthe angular results. We accomplish this using an estimate of dn/dz, theredshift distribution of galaxies in four different magnitude slices inthe SDSS photometric catalog. The resulting three-dimensional powerspectrum estimates from w(θ) and Cl agree with eachother and with previous estimates over a range in wavenumbers0.03-1)\<1. The galaxies in the faintestmagnitude bin (21*\<22, which have median redshiftzm=0.43) are less clustered than the galaxies in thebrightest magnitude bin (18*\<19 withzm=0.17), especially on scales where nonlinearities areimportant. The derived power spectrum agrees with that of Szalay et al.,who go directly from the raw data to a parametric estimate of the powerspectrum. The strongest constraints on the shape parameter Γ comefrom the faintest galaxies (in the magnitude bin21*\<22), from which we infer }, url = {http://adsabs.harvard.edu/abs/2002ApJ...572..140D}, author = {Dodelson, Scott and Narayanan, Vijay K. and Tegmark, Max and Scranton, Ryan and Budav{\'a}ri, Tamas and Connolly, Andrew and Csabai, Istvan and Eisenstein, Daniel and Frieman, Joshua A. and Gunn, James E. and Hui, Lam and Jain, Bhuvnesh and Johnston, David and Kent, Stephen and Loveday, Jon and Nichol, Robert C. and O{\textquoteright}Connell, Liam and Scoccimarro, Roman and Sheth, Ravi K. and Stebbins, Albert and Strauss, Michael A. and Szalay, Alexander S. and Szapudi, Istv{\'a}n and Vogeley, Michael S. and Zehavi, Idit and Annis, James and Bahcall, Neta A. and Brinkman, Jon and Doi, Mamoru and Fukugita, Masataka and Hennessy, Greg and Ivezi{\'c}, {\v Z}eljko and Knapp, Gillian R. and Kunszt, Peter and Lamb, Don Q. and Lee, Brian C. and Lupton, Robert H. and Munn, Jeffrey A. and Peoples, John and Pier, Jeffrey R. and Rockosi, Constance and Schlegel, David and Stoughton, Christopher and Tucker, Douglas L. and Yanny, Brian and York, Donald G.} }
