Figure Caption

Projections of the coherent \jpsi data points in (a) $\cos\theta$ and (b) $\varphi$, for events in the $-4 < y < -2.5$ rapidity interval. The curves are obtained by setting the lambda parameters in Eq.~\ref{eq:split} to the results of the fit to the distribution shown in Fig.~\ref{fig:2DHE}. The uncertainties on the data points are statistical.
