Notes. The values are: volume, box side-length, number of initial gas cells, dark matter particles, and tracers; the mean baryonic cell mass and dark matter particle mass; the gravitational softening length minimum for the gas, and the softening for the collisionless components at z = 0; the number of groups (log M200c/M⊙ from 13.0 to 14.0), lower mass clusters (14.0–14.5), intermediate-mass (14.5–15.0), and high mass (> 15.0) clusters. ( † )Effective full-volume equivalent. The TNG-Cluster numbers refer exclusively to the primary halos targeted for re-simulation.
