Consecutive images (Δt = 0.43 s) at plane (l) of figure 6 yielding a streamwise interpolation of figure 6. The weak distant legs of horseshoe 2 are initially entrained by the stronger vortices of horseshoe 3 (images a–e). Further upstream (images f–i), horseshoe 4 dominates the interaction, entraining horseshoe 2 and entraining horseshoe 3. Asymmetry results in a stronger interaction between horseshoes 2 and 3 at the top of the wake, and between horseshoes 2 and 4 at the bottom.
