In this post, I have four plots showing the ratios [math]\displaystyle{  \frac{b_{\ell}^{\text{mass cut}}}{b_{\ell}^{\text{total}}}  }[/math] for selected shells, with "total" being the kappa generated with the whole catalog (no mass cut). Similar to the power spectra (https://mocks.cita.utoronto.ca/index.php/July_26th,_2019_-_CIB_Lensing:_Kappa_Power_Spectra_Ratio_(by_Mass_Cut)_(Selected_Redshifts), note that the x-axis scales are different here) the ratio decreases noticeably at low [math]\displaystyle{  \ell  }[/math] as higher mass halos are left out, this effect is more subtle for [math]\displaystyle{  1000 \lt  \ell \lt  5000  }[/math] and virtually non-existent for [math]\displaystyle{  M_{\text{mass cut}} \le 10^{13} M_{\odot}  }[/math]. In other words, the contribution of lower mass halos ([math]\displaystyle{  \le 10^{13} M_{\odot}  }[/math]) is large at low and very high [math]\displaystyle{  \ell  }[/math], while it is significantly smaller at mid to high [math]\displaystyle{  \ell  }[/math]. However, more of the bispectrum is coming from the highest mass halos ([math]\displaystyle{  \gt  10^{14} M_{\odot}  }[/math] ) compared to the power spectrum over all multipoles and redshifts. 

(redshift 0.973 -> 3200Mpcs comoving distance or shell 8, redshift 2.029 -> 5200Mpcs comoving distance or shell 13, redshift 2.975 -> 6400Mpcs comoving distance or shell 16, redshift 3.895 -> 7200Mpcs comoving distance or shell 18)
