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

The $\eta_2(1645)$ is the lighter of the isospin singlet members of the lightest pseudotensor multiplet. It properties are not well measured and the \cite{Yao:2006px} does not include its branching ratios. The branching ratios were calculated using the values from \cite{Yao:2006px} for the ratios
\begin{eqnarray}
\frac{\Gamma(K\bar{K}\pi)}{\Gamma(a_2\pi)} &=& 0.07\pm0.03,\\
\frac{\Gamma(a_2\pi)}{\Gamma(a_0\pi)} &=& 13.0\pm2.7,
\end{eqnarray}
together with the assumption that the $K\bar{K}\pi$ mode is entirely due to $K^*K$ apart from a small contribution from $a_0(980)\pi$. We also assume that the $\eta\pi\pi$ contribution is solely due to the $a_0(980)\pi$ state. The $\eta_2(1645)$ is allowed to be off-shell by twice the width.
