1  Supersedes AULCHENKO 2003 .
2  Reanalysis of ZHOLENTZ 1980 using new electron mass (COHEN 1987 ) and radiative corrections (KURAEV 1985 ).
3  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.
5  Superseded by ARTAMONOV 2000 .
6  From a simultaneous fit to ${{\mathit e}^{+}}{{\mathit e}^{-}}$ , ${{\mathit \mu}^{+}}{{\mathit \mu}^{-}}$ and hadronic channels assuming $\Gamma\mathrm {( {{\mathit e}^{+}} {{\mathit e}^{-}} )}$ = $\Gamma\mathrm {( {{\mathit \mu}^{+}} {{\mathit \mu}^{-}} )}$.
