Misalignment : 0
Pitch : -0.3
Amplitude : 1
Mean vertical velocity for good data : 0.380 cm/s

Horizontally and vertically smoothed. Flag 1 only. --> file: fr21_leg3_fhv1.nc


Correlation between the ship's velocity and the parallel and orthognoal component of absolute velocity to the ship's velocity:
Parallel component : min max correlation :   -0.972  -0.967  
(When apply amplitude correction, values of U & V suspect. Error in correlation computation (?). Seen with Pascal Lherminier, LPO. No amplitude correction applied.)
Orthogonal component : min max correlation:  -0.117  -0.029
