Sumario:The solution of the Muskhelishvili-Omnes Integral Equation is ambiguous by a real polynomial. The coefficients of this polynomial can be fixed either by the knowledge of the low energy parameters or by the asymptotic behavior of the form factor. The role of the contact terms of the low energy effective Lagrangian is explicitly analysed.
