Re-plot of v_R and v_z for the same dust grain as in the right column of Fig. 4 (a₀ = 10 μm). The dust parameters are colored red, the surrounding gas in blue; the motion according to Eqs. (1) and (3) of Giacalone et al. (2019), with t_stop as retrieved from our model, is added in green. Especially towards larger R, the semi-analytical prescription does not reproduce the dust motion very well. It should be noted, however, that Giacalone et al. (2019) do not use it for grains this big.
