\begin{itemize}
\item Is the description present and correct?

The $f_1(1420)$ is the heavier of the isospin singlets containing only light quarks from the lightest pseudovector multiplet. The mass and width are accurately measured but while a number of decay modes have been observed \cite{Yao:2006px} does not include the branching ratios. We therefore assumed that there are only $\phi\gamma$, $K\bar{K}\pi$, $a_0\pi$ and $KK^*$ modes. The ratios 
\begin{eqnarray}
\frac{\Gamma(\phi\gamma)}{\Gamma(K\bar{K}\pi)}&=&0.003\pm0.001\pm0.001\\
\frac{\Gamma(a_0\pi)}{\Gamma(KK^*)}&=&0.04\pm0.01\pm0.01
\end{eqnarray}
  from \cite{Yao:2006px} and the ratio 
\begin{eqnarray}
\frac{\Gamma(KK^*)}{\Gamma(K\bar{K}\pi)}&=&0.78\pm0.05
\end{eqnarray}
calculated by averaging the results in \cite{Yao:2006px} are used to obtain the branching ratios. The $f_1(1420)$ is allowed to be off-shell by five times the width below the central value to ensure the decays are kinematically possible and by ten times the width above the central value.
