According Stanier et al. (2015), we need to evaluate various parameters CC ZNCC-seed , CC ZNCC-min-tol and standard error in order to deem the PIV results were correct i.e. 0.9, 0.75 and standard error less than 0.5 respectively. Can I have some relaxation in this values as instead of very small scale centrifuge tests mine is 1g model test of comparatively greater dimension of 1.8m by 1.2m.
