Left panel: redshift distribution estimates of the KiDS source catalogue (solid lines) and MICE mock source catalogue (dashed lines) in the five source tomographic bins split by photometric redshift. Right panel: number density as a function of redshift of the BOSS LRG dataset (black solid line), the MICE mock lens catalogue with the original BOSS colour selection (red dashed line), and the MICE mock lens catalogue with the adjusted BOSS colour selection (blue dotted line).
