Tomographic third-order aperture mass statistics in the KiDS-1000 data. In each panel, we show the measured statistics for a particular set of tomographic bins. The ℳ_ap³ signal is plotted as a solid blue line, while the other solid lines indicate the remaining third-order measures. We also show the mean and the 1σ error interval for the third-order aperture mass within the T17 ensemble as a dashed blue line and a blue contour. The boundaries of the 1σ error interval for the remaining aperture measures are shown as dashed and dotted gray curves.
