Comparing normalised histograms of the pixel noise (top left), PSF size (top right) and PSF ellipticity (bottom left) between KiDS-DR4 (red) and SKiLLS (blue) for the r-band images. The PSF size and ellipticity are measured from the recovered PSF image using a circular Gaussian window of sigma 2.5 pixels.
