(A) Average angle Θ and (B) its standard deviation σ(Θ) sampled with accumulated angle difference Δ A = 0.1° as a function of Ω for glass beads in four sizes. (C) Rescaled standard deviation σ/σ0 (σ0 refers to σ in the quasistatic limit in (B)) as a function of modified Froude number Fr* = Fr·D/d. Vertical dashed line locates the transition at Fr* = 0.3.
