Particle scale height Hp (top; see Eq. (20)), and root-mean-square of the vertical component of the particle speed vrms (bottom; see Eq. (21)) at the end of the sedimentation phase. The sound speed is set to cs = 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 τf ~ 0.3, lower Δ results in stronger sedimentation (lower Hp).
