SHELXL optimizes two weight parameters to bring the S value close to
1.0. This ALERT reports the S value based on the supplied sigma(I)
only. A large value of the last generally indicates the presence of
large outliers in the data set. Examples are reflections 'measured'
behind the beam stop. (See also ALERT_919). The latter are best left
out with an OMIT instruction.
