Accuracy of the numerical integration of the shear 3PCF to the third-order aperture statistics for different logarithmic spacings of radial bins, as well as for the radial binning that was used in the computation of the covariance in the T17 ensemble. All measurements were done in the SLICS ensemble. In the upper panel, we show the ratio between ⟨ℳ_ap³⟩ when estimated using a particular logarithmic bin width, b, for the shear 3PCF and the corresponding result with b ≡ 1.05. In the lower panel, we show the corresponding results when allowing for unequal aperture filters.
