Analysis of the angular distribution of the photons and mesons produced in $e^+e^-\to \psi(2S) \to \gamma\chi_{c(0,2)}$ followed by $\chi_{c(0,2)}\to \pi^+\pi^-/K^+K^-$. Gives information about the decay and is useful for testing correlations in charmonium decays. N.B. the distributions were read from the figures in the paper and are not corrected and should only be used qualatively, however the $x$ and $y$ and multipole results are fully corrected.
