Table 1.
List of spatial, mass and numerical resolution parameters for the simulations with the best resolution (i.e. TNG300-1, TNG100-1, and TNG50-1) two more simulations with the same box side-length of TNG100-1, but worse resolution (i.e. TNG100-2 and TNG100-3, and CAMELS).

Notes. The parameters are, from left to right: box side-length, initial number of gas cells and DM particles, baryon particle mass, DM particle mass, z = 0 gravitational softening length of the DM particles and minimum comoving value of the adaptive gas gravitational softening length. Values are taken from Nelson et al. (2019a). The value of ϵgas, min for CAMELS is unavailable, but it is close to the value for IllustrisTNG300-1.
