10. α, and its standard deviation, are estimated from the distribution of the velocity of the vortex center, together with the hypothesis that the transverse component is 100% of the longitudinal one (note that this number is probably excessive for a mixing layer).
11. After Brown and Roskho's experiment (Brown G.L. and Roshko A., J. Fluid. Mech. 65 (1974) 775) a considerable amount of studies have been carried out to identify, from local velocity measurements, large scale structures in turbulent flows. Here we are concerned only with small scale structures, several Kolmogorov lengths in size.
