Two-point correlation functions of galaxies with luminosity-weighting and mass-weighting are studied to determine the dependence of the clustering properties on the intrinsic properties of galaxies. The results suggest that bright galaxies with M(B) of less than -20.5 and early stage galaxies tend to be more correlated on scales of less than 14 Mpc (h = 1/2). The brightest galaxies and Sb-SC galaxies are shown to be preferentially distributed with separations of about 9 Mpc. A power law dependence of the correlation length on the limiting luminosity of the sample is found.
