Exemplary efficiencies of gas collision Q_coll, desorption Q_des, and scattering scattering Q_sca as well as the total mechanical efficiency Q_mech over alignment angle Θ and typical CNM conditions. All efficiencies are averaged over the angle β. The panels are for the different gas-dust drift of ∆s = 0.1 (top), ∆s = 1.0 (middle), and ∆s = 10.0 (bottom), respectively. We emphasize that all efficiencies are simulated for the grain with size a_eff = 400 nm and fractal dimension D_f = 2.0 depicted in the very center of Fig. 1.
