CONSTRAINED FIT INFORMATION show precise values?
 
An overall fit to 2 partial widths, combination of partial widths obtained from integrated cross section, and 3 branching ratios uses 16 measurements and one constraint to determine 5 parameters. The overall fit has a $\chi {}^{2}$ = 14.2 for 12 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, $\mathit x_{i}$ = $\Gamma _{i}$ $/$ $\Gamma _{total}$.
