Energy dependent broadening is allowed. The method Broaden allows one to broaden a spectrum object without making a copy of the object. Example description text Input dofile("definitions.Quanty") -- Broaden with a Gaussian of FWHM 0.2 and a Lorenzian with variable -- width, the interval 0 to 5.25 has FWHM=0.2. The interval 5.75,20 has -- FWHM=0.75.

The input G1 = G2 creates two pointers to the same object. Changing G1 will change G2. G1=Spectra.Clone(G2) will create two different objects.
