Notes. The cloud mass is 1000 M⊙. The size of the cloud decreases through runs A, B, C, and D, and the density increases correspondingly. The number 1 in the label denotes that the relaxation run was performed at the first refinement level. The plus and minus signs denote higher/lower maximum refinement level with respect to the canonical run. We list in the columns the run label, the ratio between free-fall time and turbulence-crossing time, the ratio between free-fall time and sound-crossing time, the initial cloud radius, the central density, the density PDF peak (as illustrated in Fig. 3) after relaxation, the initial Mach number before relaxation, the base grid refinement level, the maximum refinement level, the physical resolution, and the relaxation duration.
