VIS PSF recovered by PSFEx in the centre of the field of view. Pixel intensities are scaled on a logarithmic stretch. The image sampling is 0 . ″ 05 Mathematical equation: $ 0{{\overset{\prime\prime}{.}}}05 $ per pixel. The negative pixels close to the centre are artefacts caused by the oversampling, limited number of stars, and regularisation scheme applied by PSFEx (see Bertin 2011).
