Flux and log-luminosity distributions of objects from the mosaic in three broad redshift bins at 2.91 ≤ z< 4.00, 4.00 ≤ z ≤ 4.99 and 5.00 ≤ z< 6.64. In each panel we show the total distribution of objects (including fakes created and added to the sample through the process described in Sect. 5.2) in a coloured hatched histogram. We overlay the distribution of observed objects in filled blue bars. The final samples, curtailed at the 25% completeness limit in flux (Δ f = 0.05) for the median redshift of objects in the redshift bin is overplotted in a bold cross-hatched black histogram. Overlaid on each panel are the completeness curves as a function of flux (or log luminosity) at each redshift (Δ z = 0.01) falling within the bin. Each redshift is given by a different coloured line according to the colour-map shown in the colour bar, and the curve at the median redshift of the bin is emphasized in black. The median redshift of the bin is also given by a black line on the colour bar.
