Values, errors and correlations of the fit parameters are listed by command FRES.
The command FLIST produces an output of fit function values and experimental data.
Under some circumstances it may be preferable to determine sum and moments
of raw data or raw data minus background fit in an interval rather than peak fitting.
Command FSUM calculates the sum and first to third moments
of a distribution y(x(i)):

   Sum      = Sum(i) y(i)
   Mean     = Sum(i) y(i)* x(i) / Sum
   Variance = Sum(i) y(i)*(x(i)-Mean)**2 / Sum
   Skewness = Sum(i) y(i)*(x(i)-Mean)**3 / Sum
 
Graphs of the total fit function, selected components or single peaks
are shown by command FDISP.
