Posterior constraints with different minimum halo mass cuts. The contours denote the 3σ constraints from 500 lens systems. Even removing the lowest mass halos below ﹩{m}_{{\rm{halo}}}\leqslant 7.5\,{\mathrm{log}}_{10}{M}_{\odot }﹩ induces a noticeable shift relative to the full sample. Additionally, the posterior estimates seem to broaden when low-mass halos are removed.
