Analysis of the angular distribution of the baryons produced in $e^+e^-\to J/\psi,\psi(2S) \to \Lambda^0\bar\Lambda^0, \Sigma^0\bar\Sigma^0$. Gives information about the decay and is useful for testing correlations in hadron decay. Beam energy must be specified as analysis option "ENERGY" when rivet-merging samples.
