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

The $a^+_0(980)$ is the charged member of the lightest scalar isospin triplet. The measurement of the $a_0$ parameters is complicated because it is close to the $KK$ threshold. We chose to use a Flatte parameterisation from \cite{Bugg:1994mg} ,\cite{Rubin:2004cq}  for the lineshape. We therefore take the mass from this paper. As we are using this parameterisation for the lineshape the width is not used and the value given is simply the value for an on-shell $a^+_0(980)$ from the parameterisation. The partial widths from the Flatte parameterisation are used to determined the branching ratios which vary with the off-shell mass. The branching ratios in the table are therefore not used. The values given are indicative and were calculated in $D^0\to a_0^+K^-$ decays.
