XX- Data processing 
The current statistics are calculated from low-passed data 
(Gaussian low-pass, cut-off period 48 s ). Mean values are marked 
by an overbar. The mean values of u and v are given together 
with the 95% confidence interval assuming a Gaussian normal 
distribution: 
i/uTu? 
mean value * 1.96-*—— , n = number of cycles. 
The Lagrangian statistics were calculated according to 
Taylor (1921).
