Temporal separation between the two i-band passes, as a function of position on-sky. The figure shows all KiDS DR5 pointings, coloured by the number of years separating the two i-band passes. The overall distribution of these values is shown as a KDE within the colour bar, computed with a 0.1-year rectangular bandwidth. The largest temporal separations occur typically in the GAMA fields, where KiDS observations were focussed during early survey operations. The shortest temporal separation between any two passes is at RA = 350.3 deg, Dec = −35.1 deg, which was observed on 21 August 2017 and 7 October 2017 for the two i-band passes, respectively, for a separation of 50 nights.
