A multiparticle fit to ${{\mathit \chi}_{{c1}}{(1P)}}$, ${{\mathit \chi}_{{c0}}{(1P)}}$, ${{\mathit \chi}_{{c2}}{(1P)}}$ and ${{\mathit \psi}{(2S)}}$ with 4 total widths, partial width,25 combinations of particle width obtained from integrated cross section,84 branching ratios uses 248 measurements and one constraint to determine 49 parameters. The overall fit has a $\chi {}^{2}$ = 378.1 for 200 degrees of freedom.
The following off-diagonal array elements are the correlation coefficients <$\mathit \delta $x$_{i}$~$\delta $x$_{j}$> $/$ ($\mathit \delta $x$_{i}\cdot{}\delta $x$_{j}$), in percent, from the fit to parameters ${{\mathit p}_{{i}}}$, including the branching fractions, $\mathit x_{i}$ =$\Gamma _{i}$ $/$ $\Gamma _{total}$. The fit constrains the ${{\mathit x}_{{i}}}$ whose labels appear in this array to sum to one.
