Fig. 9. Graph of relative lift L_r against time through the angle series experiments. The usual red/green/blue colour coding of the locusts applies. The horizontal black line denotes the equilibrium level of relative lift production. Coloured lines join the 14 reference measurements at _b,ref. The vertical range of the lines gives an indication of how lift production varies through time. The range of scatter about the lines gives an indication of the relative magnitude of variation in lift due to changes in _b.
