Structure and formation of superclusters - VII. Distribution of bright and faint galaxies in the Virgo supercluster.

The spatial distributions of bright and faint galaxies in the Virgo supercluster are compared using the nearest neighbour test and cluster analysis. There are no differences in the spatial distribution of bright and faint galaxies down to the absolute magnitude -15.0 (H=100 km s^-1^ Mpc^-1^). Bright and faint galaxies are situated in statistically identical systems, and the ratio of faint/bright galaxies is nearly the same in high- and low-density regions.
