\section{Model independent \section{Model-independent  H and D_{\rm A} constraints from reconstructed clustering wedges} \textit{Here Eyal describes results of the H, Da measurements from the reconstructed wedges. }   Here we apply the techhnique of reconstruction of the baroynic acoustic feature on the WiggleZ data, present the results in the form of clustering wedges, and describe the model-independent  constraints on $H$ and $D_{\rm A}$. We test our methodology and compare our results with those obtained when applied on the WiZCOLA mocks. In \cite{Kazin_2014} we reported application of the reconstruction of the density field technique,   and have shown it useful for sharpening of the baryonic feature, and hence improved usage as a standard ruler. \cite{Eisenstein_2007} showed that the blurring of the baryonic peak due large-scale coherent motions of galaxies could be remidied by using the density-field information. In practice this procedure involves estimating the linear displacement vectors $\vec{\psi}$ of the galaxies in grid-cells of length 5 $h^{-1}$Mpc, and shifting them by $-\vec{\psi}$.
