Real (red) and imaginary (blue) parts of the first natural component of the shear three-point correlation function Γ⁽⁰⁾. Each plot panel corresponds to one fixed triangle shape shown in the bottom-right corner; the x-axis represents the length of the red triangle shape. We compare an integration of the analytic bispectrum model (B.9, dark solid) and the analytic solution (B.8, light dashed). Under each panel we show the difference between the integration and the analytic solution, multiplied by a factor of 10⁵ for visibility.
