Upper panel: Farpoint halo mass function measurements at redshifts z = 0 and z = 1. We compare the results to the mass function emulator of Bocquet et al. (2020). Middle and lower panels: ratio of the simulation and the emulator results at both redshifts. Note that the emulator only provides predictions down to M_200c ∼ 10¹³h⁻¹ M_⊙. For the mass range covered, the agreement is excellent and within the accuracy bounds reported in Bocquet et al. (2020).
