Convergence bispectrum for sources at redshifts z_s = 0.6,1, and 1.5, for equilateral triangles. The points are the results from numerical simulations with 3-σ error bars. The low black dashed line “L” is the tree-order bispectrum (28), the “1-loop” dot-dashed black line is the prediction of 1-loop standard perturbation theory, which is identified with our 3-halo term (14), the green dotted line “2H” is the 2-halo contribution (15) and the upper blue dashed line “1H” is the 1-halo contribution (16).
