Varying end-detach rates. Variation of vorticity, motor density and fraction of [+]-end motors with kE for kA/kD = 35 and kmτ
= 7.5 × 10-3 (solid lines, filled squares) and kA/kD = 60 and kMτb = 37.5 × 10-3 (dashed lines, open diamonds). P/P0 = 0.024 in both cases. The thick dashed line in the lower plot corresponds to 25%. Quantities were measured just prior to contraction, or in steady-state if there was no contraction or it happened too rapidly to discern.
