Notes. For B22, the labels Empirical, EAGLE, ILLUSTRISTNG, and MILLENNIUM refer to different prescriptions for the star formation rate density evolution. For T23, the fiducial and −3σ models assume different rates of the ¹²C(α,γ)¹⁶O reaction. The values from G24 are obtained assuming different metallicity dispersions ${\tilde{σ}}_{Z}$ ${\tilde \sigma _{\rm{Z}}}$ and metallicity thresholds Z_th, for PISN.
