Circular velocity profiles of four randomly selected clumps at ﹩z=2.0﹩. The circular velocities are estimated by ﹩[ GM( < r) / r] ^{1/2}﹩, where r is the distance from the center of the clump and ﹩M( < r) ﹩ is the mass within r. We plot from 0 to 3r_sub for r. The upward‐pointing arrows indicate the positions of the r_sub values, and the open circles represent the minimum points of the circular profiles.
