PD and PGL of the radiation pattern in three situations: (1) with gravitational influence but without actuator adjustments or NEOD, which is denoted by GO (gravity only, first bar in each panel); (2) with gravitational influence and actuator adjustments, but without NEOD (second bar in each panel); and (3) with gravitational influence, actuator adjustments, and random NEODs (third to fifth bars in each panel).
