Statistical and systematic errors combined. From a fit with floating $\mathit M2$ amplitudes $\mathit a_{2}$ and $\mathit b_{2}$, and fixed $\mathit E3$ amplitudes $\mathit a_{3}=\mathit b_{3}$=0. Not independent of values for $\mathit a_{2}({{\mathit \chi}_{{c2}}{(1P)}}$) and $\mathit b_{2}({{\mathit \chi}_{{c2}}{(1P)}}$) from ARTUSO 2009 .
