Zero-point corrections estimated in KiDS+KiDZ using SLR. Left: difference between SLR offsets estimated using i₁ photometry and i₂ photometry, prior to recalibration of the u-band zero-points. Centre: differences between SLR offsets estimated using 0″.7 minimum-radius aperture fluxes and 1″.0 minimum-radius aperture fluxes (see Sect. 3.6). Right: distribution of final SLR offsets used in DR5 (i.e. corrections to the nightly zero points derived from photometric standards), including Gaia recalibration.
