CONSTRAINED FIT INFORMATION show precise values?
 
An overall fit to 4 branching ratios uses 5 measurements to determine 3 parameters. The overall fit has a $\chi {}^{2}$ = 2.6 for 2 degrees of freedom.
 
The following off-diagonal array elements are the correlation coefficients <$\mathit \delta $p$_{i}\delta $p$_{j}$> $/$ ($\mathit \delta $p$_{i}\cdot{}\delta $p$_{j}$), in percent, from the fit to parameters ${{\mathit p}_{{{i}}}}$, including the branching fractions, $\mathit x_{i}$ = $\Gamma _{i}$ $/$ $\Gamma _{total}$.
