A multiparticle fit to ${{\mathit J / \psi}{(1S)}}$, ${{\mathit \eta}_{{{c}}}{(1S)}}$, ${{\mathit B}^{\pm}}$, ${{\mathit \psi}{(2S)}}$ and ${{\mathit h}_{{{c}}}{(1P)}}$ with the total width, 10 combinations of partial widths obtained from integrated cross section, and 39 branching ratios uses 118 measurements to determine 19 parameters. The overall fit has a $\chi {}^{2}$ = 216.3 for 99 degrees of freedom.
 
The following off-diagonal array elements are the correlation coefficients <$\mathit \delta $p$_{i}\delta $p$_{j}$> $/$ ($\mathit \delta $p$_{i}\cdot{}\delta $p$_{j}$), in percent, from the fit to parameters ${{\mathit p}_{{{i}}}}$, including the branching fractions, $\mathit x_{i}$ = $\Gamma _{i}$ $/$ $\Gamma _{total}$.
