Comparison of statistics of the scaled photo-z bias δz = (z_B − z_spec)/(1 + z_spec) of the KV450 (red) and MICE2 mock (blue) datasets. The galaxies used for this compilation originate from DEEP2, VVDS, and zCOSMOS. The columns from left to right show statistics as a function of spectroscopic redshift, photometric, and r-band magnitude (shown as histograms in the bottom row). The rows from top to bottom show the median-absolute-deviation (σ_m), mean (μ_δz), and the outlier fraction (ζ_0.15, the fraction of objects with δz >  0.15).
