Abstract content
It is clearly demonstrated that Gounaris-Sakurai pion EM FF model at the elastic region is not enough accurate for a determination of the $\rho^0(770)$ parameters. Then in no case it can be exploited even for a determination of the excited $\rho(770)$ parameters from whatever precise data on the $e^+e^-\to \pi^+\pi^-$ and $\tau^-\to \pi^-\pi^0\nu_{\tau}$ processes.
