Mass-size relation of ellipsoidal clusters with mass infall along the edge (top), with mass infall along the pole (middle), and with a more realistic and uniform infall estimation (bottom); all of the other parameters are the same as that of the anisotropic model in Fig. 7. The clusters become more spherical when accretion comes from the sides, while they are completely flattened when flows come from the pole directions. The results are almost unaltered compared to that without ram pressure in the case where the accretion comes from all directions, except that the range of solution is slightly increased owing to ram pressure confinement. In all three cases, the mass-size relation does not differ too much from one another.
