PDZ metrics for the color-space weighted spectroscopic sample. Top: number of sources in the bin. The histogram of the distribution for the sources in the bins according to their spec-zs is shown in gray. Middle: fraction of the stacked-and-shifted PDZs in 0.05(1 + z) (F₀₀₅). Bottom: fraction of the stacked-and-shifted PDZs in 0.15(1 + z) (F₀₁₅) for all the tested methods. Fractions close to 1 in a bin indicate good results.
