Detection significance for proto-clusters for the redshift range z = 1.5 − 2 (top) and z = 3 − 4 (bottom). For the galaxy selection a redshift interval corresponding to Δz (50%) was used. Top: A detection aperture of 5 arcmin was applied with a local background assessment. Bottom: An aperture of 7 arcmin was used.
