Photometric redshift-dependent photo-z scatter and outlier fractions for the photo-z estimators used in this paper as compared to available spec-zs in Stripe 82 with i < 22.5 and 0.01 < z_spec < 0.8. The 3σ-clipped dispersion (σ_z) is indicated by the solid lines and symbols. The redshift error has not been divided by (1 + z). The dashed lines plot f_outlier, the fraction of photo-zs that deviate by more than 3σ; this is a more stringent definition than f_catastrophic sensitive to systematic patterns of scatter that can bias certain redshift bins.
