 Left: Distribution of $\Delta \rm{M}$ for d+\dbar\ in the $2.2~\leq$~\pt~$< 2.4$~\gmom\and centrality interval 30-40\% fitted with a Gaussian with an exponential used to reproduce the signal andan exponential to reproduce the background Right: The \vtwo$^{\rm{Tot}}$ vs $\Delta \rm{M}$ for d+\dbar\ for 2.2~$\leq$~\pt~$<$~2.4~\gmom\in events with 30-40\% centrality. Points represent the measured $v_2^{\mathrm{Tot}}$,while the curve is the fit performed using equation~\ref{eq:v2tot}.
