Figure 4: Stochastic particles simulations.
(a) Ten (of 1,000) stochastic particle trajectories of an R particle (Fig. 3a) for Peclét number, Pe=1. (b) Histogram showing the corresponding distribution of drift velocities 
for Pe=1. (c) Average drift velocity 
as a function of Pe for chiral particles (R and S) shown in Fig. 3a; the calculated (calc) drift velocity is scaled by the magnitude of chiral drift |vc| in the absence of Brownian motion. The error bars represent 95% confidence intervals on the mean drift velocity based on 1,000 realizations of the stochastic process.
