** Note ) **

We do not scale the error of an average
(as is presently done by the Particle Data Group )
in case &chi^2/dof &> 1, where dof is the number of
degrees of freedom in the average calculation.
In this case, we examine the systematics of each measurement and
try to understand them.
Unless we find possible systematic discrepancies between the measurements,
we do not make any special treatment for the calculated error.
We provide the confidence level of the fit so that
one can know the consistency of the measurements included in the average.
We attach a warning message in case that some special treatment is done
or the approximation used in the average calculation may not be good enough
(* eg,*
Gaussian error is used in averaging though the likelihood
indicates non-Gaussian behavior).
