A new high-precision measurement of the reaction at a beam momentum of 2.95 GeV/c with more than 200 000 analyzed events allows a detailed analysis of differential observables and their inter-dependencies. Correlations of the angular distributions with momenta are examined. The invariant mass distributions are compared for different regions in the Dalitz plots. The cusp structure at the threshold is described with the Flatt, formalism and its variation in the Dalitz plot is analyzed.
