Plots of total speed and the radial velocity component vs heliocentric distance for the nanodust particles (Q/m = 10⁻⁴e/m_p) released just outside of the trapping region for different assumptions about plasma corotation: no corotation (solid line), maximum corotation (dotted line), and the model of Weber and Davis (dashed line). To extend the corotation region, the Alfvén radius was artificially set at 0.5 AU.
