Galaxy counts in proto-clusters (red) in comparison to the background (blue) as a function of the total galaxy number in the proto-clusters. The top row was taken in the redshift range z = 1.5 − 2 with an aperture of 0.5 rpc and the bottom row in the range z = 3 − 4 inside an aperture of rpc. For the galaxy selection a redshift interval corresponding to Δz (50%) was used.
