Cumulative M_bound HMF of the Flagship haloes compared to the T08, D16 and C17 halo mass functions at redshift z = 0.1. In the top panel we show the cumulative HMFs (colours indicated in the legend). The lower panel shows the ratio of the cumulative M_bound HMF to the other cumulative HMFs. The dotted line serves as a reference point where the cumulative HMFs are the same. Values of M_bound > 10¹⁴ h⁻¹ M_⊙ are omitted, since shot noise is dominant due to the small volume available at z = 0.1 in the lightcone.
