TOPz feature comparison in three magnitude ranges (different panels). The coloured lines show the cumulative fraction of objects with a certain photo-z accuracy. Each coloured line represents a different TOPz run with certain features turned on or off, as described by the legend on the top panel. The three panels have different sets of galaxies based on their Z-band magnitude (as shown in the bottom-right corner of each panel). The dashed black line indicates the 90% fraction to help better distinguish the accuracies on each panel. See Fig. 19 for the differential distribution of differences between spectroscopic redshifts and photo-z.
