CONSTRAINED FIT INFORMATIONshow precise values?

 
An overall fit to 5 branching ratios uses 6 measurements and one constraint to determine 4 parameters. The overall fit has a $\chi {}^{2}$ = 1.4 for 3 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.
