Top panels: convergence bispectrum at z = 1 extracted from the MS (orange) and modelled from BIHALOFIT (blue). Bottom panels: ratio of measurement over the model. The error bars denote the error on the mean of all 64 lines of sight. For each point, we compute the average in a bin of width Δℓ = 0.13ℓ, both in the measurements and the model. For the model, we use equation (8) of Joachimi et al. (2009) as a weight for different triangle configurations within one bin.
