The table agrees entry by entry with Table~1 of \cite{Sen11positivity}. Entries with $Q\cdot P<0$ are the other chamber's values at $|Q\cdot P|$ by the symmetry $v\mapsto -v$; their negativity for $Q\cdot P\le -1$ is the two-centred contribution of Theorem~\ref{thm:wallcrossing}.} \label{tab:phi10} \end{table*}
