The present analysis provides a suitable parameterization for reproducing the measured form factor in the whole energy region and allows to extract the corresponding low-energy parameters together with a prediction of its values at the origin, related to $\\Gamma_{\\eta^\\prime\\to\\gamma\\gamma}$, and the asymptotic limit.
