CONSTRAINED FIT INFORMATION show precise values?

 An overall fit to total width, 8 combinations of particle width obtained from integrated cross section,19 branching ratios uses 93 measurements and one constraint to determine 13 parameters. The overall fit has a $\chi {}^{2}$ = 117.8 for 81 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.
