RSCG 7 and RSCG 8. Left: Galaxy positions on the sky. Filled squares are galaxies in the RSCG, filled circles are galaxies in the RSCG environment, open circles are foreground/background galaxies, and crosses are galaxies without measured velocities. Right: Velocity distributions. The upper histogram includes all galaxies with measured redshifts. The lower histogram expands the region around the RSCG. Hatched regions are the RSCG environment; filled regions are the RSCG itself.
