Notes. Column (1) gives the upper bound of the redshift interval with width Δz = 0.5, Column (2) shows the volume per deg2 in units of 106 Mpc3, Columns (3–6) provide the number of proto-clusters in this volume with mass > 1014, 2 × 1014, 5 × 1014 and 1015 M⊙, respectively, Columns (7,8) give the physical radii of proto-clusters with masses of 1014 and 1015 M⊙, and Column (9) shows the sky area covered by a proto-cluster with a mass ≥1014 M⊙.
