Δ_z as a function of redshift in the mass-selected sample, from M _⋆  ≥ 10¹¹  M_⊙ (thiner line) to 10¹⁰  M_⊙ ≤ M _⋆  < 10^10.2  M_⊙ (thicker line) galaxies in bins of 0.2 dex. The black solid line marks the photometric errors of blue galaxies in the lower mass bin, while the black dashed line is for red galaxies in the same mass bin. The vertical line marks the higher redshift in our samples, z_max = 1.1. The horizontal line marks the median Δ_z for low-mass galaxies at the high redshift end of our sample 1.0 ≤ z < 1.1, Δ_z = 0.015.
