Particle scale height H_p (top; see Eq. (20)), and root-mean-square of the vertical component of the particle speed v_rms (bottom; see Eq. (21)) at the end of the sedimentation phase. The sound speed is set to c_s = 800ms^-1. Half of the simulations (red squares) have a standard pressure support (Δ = 0.05) and the other half (blue triangles) have a reduced pressure support (Δ = 0.025). For particles smaller than τ_f ~ 0.3, lower Δ results in stronger sedimentation (lower H_p).
