Figure 2.13 Spanwise correlalion coefficienl Rp between ihe fluctuating pressures measured on a vibrating pivoted rigid 

 cylinder in a deep boundary layer flow; from reference 20. The peak-io-peak tip displacement amplitude of the cylinder is 

 given by 2 Y/ D and the spanwise separation between the pressure taps is given by !^z/ D. Reynolds number = 75,000.
