Measured and modelled E_n vector for the first five moments in the T17 mock data. The green and blue dots are the mean of all 1944 KiDS-1000 mock data that are also used to compute the covariance matrix with a resolution A_pix = 0.18 arcmin² and shape noise. The red dots represent the data vector measured from one full-sky T17 realisation with a resolution A_pix = 0.18 arcmin² and no shape noise. The grey band indicates the expected uncertainty from the KiDS-1000 survey.
