Description:
  'Measurement of the cross section for $e^+e^-\to J/\psi + \pi^+\pi^-$, $\pi^0\pi^0$ or $K^+K^-$
   at $\sqrt{s}=4.015$, $4.160$ or $4.260\,$GeV to study the properties of $\psi(4040)$ , $\psi(4160)$ and $Y(4260)$ (now $\psi(4230)$).
   Two modes are provided, one for the $e^+e^-$ cross secions (MODE=SIGMA) and a second which implements the measured mass distribution in $Y(4260)\to J/\psi\pi^+\pi^-$ decays. There is no consensus as to the nature of the $\psi(4230)$ $c\bar{c}$ state and therefore we taken its PDG code to be 9030443, i.e. the first unused code for an undetermined spin one $c\bar{c}$ state. This can be changed using the PID option if a different code is used by the event generator performing the simulation.'
