  In the last years it has been revealed that if measuring relative to higher
order event planes $\Psi_n$, higher order flow coefficients $v_n$ for $n>2$ can
be measured. It also turned out that Bose-Einstein (HBT) correlation radii also
show 3rd order oscillations if measured versus the third order event plane
$\Psi_3$. In this paper we investigate how these observables can be described
via analytic hydro solutions and hydro parameterizations. We also investigate
the time evolution of asymmetry coefficients and the mixing of velocity field
asymmetries and density asymmetries.
