Relative difference between different HMF predictions from other works found in the literature and e-MANTIS, for the reference P18 cosmology and at different redshifts. Solid lines correspond to predictions from fits to simulations, and dashed lines to emulators. Left: FoF haloes with b = 0.2. Right: SO haloes with Δ = 200c. The light and dark shaded areas mark the ±5% and ±10% levels, respectively.
