Monte Carlo simulations are used to compute the centrality dependence of the odd moments of the initial eccentricity $\epsilon_{n+1}$, relative to the even order (n) participant planes $\Psi^*_n$ in Au+Au collisions. The results obtained for two models of the eccentricity -- the Glauber and the factorized Kharzeev-Levin-Nardi (fKLN) models -- indicate magnitudes which are essentially zero. They suggest that a possible correlation between the orientations of the the odd and even participant planes ($\Psi^*_{n+1}$ and $\Psi^*_n$ respectively), do not have a significant influence on the calculated eccentricities. An experimental verification test for correlations between the orientations of the the odd and even participant planes is also proposed.
