Mass central value and systematic error recalculated by us according to Eq.$~$(16) in ARMSTRONG 1993B, using the value for the ${{\mathit \psi}{(2S)}}$ mass from AULCHENKO 2003.
4
From a sample of ${{\mathit \eta}_{{{c}}}{(1S)}}$ and ${{\mathit J / \psi}}$ produced in ${{\mathit b}}$-hadron decays. Systematic uncertainties not estimated.
6
From a simultaneous fit to ${{\mathit e}^{+}}{{\mathit e}^{-}}$, ${{\mathit \mu}^{+}}{{\mathit \mu}^{-}}$ and hadronic channels assuming $\Gamma\mathrm {({{\mathit e}^{+}} {{\mathit e}^{-}})}$ = $\Gamma\mathrm {({{\mathit \mu}^{+}} {{\mathit \mu}^{-}})}$.
