Caption: Figure 5.

Same as Figure 4 but considering the effects of f high-J ranging from 50% (left panel) to 100% (right panel). A fixed dust-to-gas ratio of 0.01 is assumed. The RAT-D mechanism becomes more efficient when applied on grains at high-J attractors, resulting in decreased disruption grain sizes with increasing f high-J .
