Stitched point spread function (PSF) from combining stars within different magnitude ranges (see text) from all fields with updated background-subtracted images. The colours and line styles indicate the radial range where different groups of stars (core, intermediate, outer 1, and outer 2) contributed to constructing the total PSF. The brown solid line shows the PSF constructed in the same way as above from standard KiDS data-release 4 images. The excess of faint light beyond 200 pixels in the PSF from the updated pipeline indicates the missing light in the standard KiDS pipeline.
