CONSTRAINED FIT INFORMATION show precise values?

 An overall fit to total width,10 combinations of particle width obtained from integrated cross section,21 branching ratios uses 97 measurements and one constraint to determine 15 parameters. The overall fit has a $\chi {}^{2}$ = 120.8 for 83 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.
