Non-tomographic third-order aperture measures in the KiDS-1000 data, using only equal aperture scales (left) or a combination of different scales (right). The error corresponds to the standard deviation in the T17 ensemble. The solid black line compares our measurement to the mean value of the T17 ensemble and the dotted black line corresponds to the result when rescaling the measurement in the T17 ensemble to a cosmology for which the values of Ω_m and S₈ correspond to the best-fit values from A21.
