With the number of subtractions we are using, the effects generated by the final state interaction are dominated by low energy $\\pi\\pi$ scattering. Since the corresponding phase shifts are now accurately known, causality and unitarity determine the decay amplitude within small uncertainties -- except for the values of the subtraction constants.
