Notes: Columns are: the label, the density nad at which the eos switches from isothermal to adiabatic as defined in Eq. (1), the minimum density nsink at which the sink is introduced, the polytropic index γ, the maximum refinement level lmax, and the physical resolution. The temperature remains 10 K at density below nad. When the full eos is used, the second and third adiabatic index switches occur at 30 nad and 30 000 nad, corresponding roughly to 100 K and 1000 K, respectively. In the labels, “C/I” stands for adiabatic/isothermal eos, the number is the value of nad, “h/s/f” stands for hard/soft/full eos, “+/–” is for higher/lower resolution, “d” stands for higher sink density threshold, the asterisk represents a stricter clump merging scheme, and “o” stands for density threshold criteria for sinks alone.
