The box size, resolution and duration (in orbits) of the simulations are given in columns two, three and four. The time averaged properties of the turbulence, i.e.~the value of~$\alpha$ (total stress normalized by the thermal pressure) and the velocity fluctuations along the three spatial (normalized by the speed of sound) appear in the following four columns. \end{table}
