Clump axis ratio distribution in runs hyd, hydg, mhd1r, and mhd1t at about 2 Myr (top), and at the end of each run (bottom). The end of runs hyd, hydg, and mhd1r is at about 6 Myr, and the end of run mhd1t is at about 7 Myr. The histograms on the left show the ratio of the shortest (μ₁) to the second longest (μ₂) dimension of the structure, and those on the right show the ratio of the second longest to the longest (μ₃) dimension of the structure. Clumps containing less than 10 cells are not shown.
