Redshift residuals of the z_CNN and z_web for the GAMA survey. Top: differential histograms with the full sample for the z_CNN (green) and the z_web (with the mode, median, and mean of the PDF) at 17.8 ≤ r ≤ 18.8 (left), and 18.8 ≤ r ≤ 19.8 (right). Bottom left: cumulative histograms for the z_CNN (dashed line) and z_web (median only, solid line) at low redshift (z ≤ 0.17) and split into two magnitude bins (red: 17.8 ≤ r ≤ 18.8; blue: 18.8 ≤ r ≤ 19.8). Bottom right: same as left, but at high redshift (0.17 ≤ z ≤ 0.4).
