FDM halo mass cut for TNG50 merged satellites: DM mass as a function of time for all merged satellites in the entire TNG50 sample. The hexagonal bins represent at least one satellite. The solid lines represent the low halo mass cutoff for different values of m₂₂. The cutoff for m₂₂ = 0.3 (1.0) removes 6.4% (1.12%) of all satellites between z = 2 and z = 0. For m₂₂ ≥ 7, no halos are removed.
