An overall fit to 15 branching ratios uses 51 measurements andone constraint to determine 10 parameters. The overall fit has a

χ2 = 51.8 for 42 degrees of freedom.

The following off-diagonal array elements are the correlation coefficients〈

WEIGHTED AVERAGE1.49±0.13 (Error scaled by 1.3)

Values above of weighted average, error,and scale factor are based upon the data inthis ideogram only. They are not neces-sarily the same as our ‘best’ values,obtained from a least-squares constrained fitutilizing measurements of other (related)quantities as additional information.
