First two natural components of the shear 3PCF on a catalog with ≈3.1 × 10⁵ shapes on a 100 deg² area. We fixed two triangle sides and varied the enclosing angle, ϕ. Solid lines indicate the real part of the 3PCF, while dashed lines stand for the imaginary part. The regions between the dashed black lines correspond to the intervals in which the ordering of the lengths of the triangle is constant. We note that due to the different binning parameterizations of TREECORR and our estimator, we do not expect perfect agreement between the curves.
