Ks-band AB Petrosian magnitude versus redshift. This plot shows very few redshifts greater than z = 1, shown in red squares. The galaxies with z > 1 are likely to have spectroscopic redshifts, whereas the photometric redshifts are limited to 0 < z < 1. Galaxies with Ks_AB < 18.2 tend to have z < 1, so we have selected a sample in TOPCAT which have Ks < 18.2 and z < 1, which are shown in light green dots.
