Weighted average for the LBG counts, after correcting for completeness. The average is based on all 3 fields until R = 25.5 and, for fainter magnitudes, only the two deepest fields are considered (Q1623 and COSMOS), with a conservative cut made at ~80% completeness. We also show the double power law fit of this curve and the derived values for α = 1.04 and β = 0.13, m∗ = 25.01 and log N∗ = 0.39, where N is the number of galaxies per arcmin2 per 0.5 mag bins. The dotted lines show the upper and lower limit curves.
