Table 1 Table of physical and numerical parameters for each of the resolution levels of the three flagship TNG simulations. The physical parameters are: the box volume, the box side-length, the initial number of gas cells, dark matter particles, and Monte Carlo tracer particles. The target baryon mass, the dark matter particle mass, the z = 0 Plummer equivalent gravitational softening of the collisionless component, the same value in comoving units, and the minimum comoving value of the adaptive gas gravitational softenings. Additional characterizations of the gas resolution, measured at redshift zero: the minimum physical gas cell radius, the median gas cell radius, the mean radius of SFR > 0 gas cells, the mean hydrogen number density of star-forming gas cells, and the maximum hydrogen gas density
