Holds the variables of PIV data.
This structure is primarly intended for locations, (PIV) estimators (i.e. particle image displacements) and some stastistics, like mean, minimum, maximum and standard deviation or rms values. But might be used for any vectorial quantity. Quantities in z-direction have not yet been implemented by the library functions, though.

gfloat** __GpivPivData::snr |
signal to noise ratio.
The value has been defined as the ratio between the first and second highest covariance peak, In case validation takes place (during iterative interrogation or during a validation step after image interrogation), the snr value is used as the residual value between actual and surrounding estimators
