Description
It is demonstrated, if data on the EM form factors of the nonet of pseudoscalar mesons $\pi^+$, $\pi^0$, $\pi^-$, $K^+$, $K^0$, $\bar K^0$, $K^-$, $\eta$, $\eta'$ are described by the $Unitary \& Analytic$ model, then with more precision the muon $g-2$ anomaly and QED running fine structure constant at the squared mass of the Z-boson $\alpha(M^2_Z)$ are evaluated The most important sources contributing to the error reduction of quantities under consideration are:
\begin{itemize}
\item The $Unitary\& Analytic$ model of the corresponding form factors provides a function behaving smoothly at small $\delta t$.
\item Also experimental data outside the integration region are exploited for determination of the errors of parameters of the model.
\item Theoretical knowledge of form factors, which by a construction respect their all known properties.
\end{itemize}
