Figure Caption
Sketch of the \Dstar-meson decay and the reference frames considered for the spin alignment measurement, namely the helicity and production ones. The momentum vectors of the decay products \Dzero and $\uppi^+$ are considered in the rest frame of the parent \Dstar meson and the $\vartheta^*$ angles are between the momentum of the $\uppi^+$ and the two quantisation axes.
