Broaden

Broadens a spectrum by a Gaussian and Lorenzian. Energy dependent broadening is allowed. The method Broaden allows one to broaden a spectrum object without making a copy of the object.

Input

Example.Quanty
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 interval 5.25 to 5.75 linearly increases from 0.2 to 0.75
 
GBroaden = Spectra.Broaden(G, 0.2, {{0.0,0.2}, {5.25,0.2}, {5.75,0.75}, {20.0,0.75}})
