CONSTRAINED FIT INFORMATION show precise values?
 
An overall fit to the total width, 4 partial widths, combination of partial widths obtained from integrated cross section, and 6 branching ratios uses 44 measurements and one constraint to determine 8 parameters. The overall fit has a $\chi {}^{2}$ = 82.3 for 37 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, $\mathit x_{i}$ = $\Gamma _{i}$ $/$ $\Gamma _{total}$.
