After summarizing the properties of the socalled Dalitz Array (DA), which is a genuine characteristics of a resonance, we determine those of the well known ε, γ, andA2 resonances produced in theK−p→π+π−π0Λ final state at 4.2 Ge V/c. A tentative measurement of the DA of theA1 meson produced backwards in the reactionK−p→π+π+π−Σ− is also presented. The data for this analysis come from the high statistics (130 events/μb) experiment performed by the ACNO Collaboration.
