Abstract
The luminosity dependence of clustering in galaxy distributions is analysed using the CfA redshift catalogue, where the magnitude correction for both Galactic and internal extinction is taken into account. It is found that, contrary to previous results, the luminosity dependence of clustering is very weak when the magnitude correction is made, showing no evidence of a positive dependence (luminosity segregation) in the magnitude ranges of interest. The results are not consistent with the luminosity segregation predicted in standard biased cold dark matter scenarios. The morphological dependence is also investigated further. The late-type galaxies cluster in the same way for most magnitude ranges after the magnitude correction. There is even some antisegregation, whereby faint galaxies cluster more strongly than luminous ones
