| Summary:
The reaction $e^+ e^- to (D_s^{*+} D_s^- + {rm c.c.})$ has been used with great success at the CLEO-c detector, and will be a source of valuable future data from the BES-III detector, to obtain information about the properties and decays of the $D_s$ and $D_s^*$. The angular distributions of the $D_s^*$ and the final-state particles in $D_s^* to D_s γ$ are needed to model the decays properly, to confirm the spin-parity assignment $J^P(D_s^*) = 1^-$, and to model the acceptance for the rare process $D_s^* to D_s e^+ e^-$. This note presents some of the necessary expressions.
