Description:
  'Mass distribution in $Y(4260)\to J/\psi\pi^+\pi^-$ decays ($Y(4260)$ is now $\psi(4230)$).
  The background subtracted data were read from figure 3 in the paper.
  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.'
