 +====== Broaden ======
  
 +###
 +Broadens a spectrum by a Gaussian and Lorenzian. Energy dependent broadening is allowed. The method //[[documentation:language_reference:objects:spectra:methods:broaden|Broaden]]// allows one to broaden a spectrum object without making a copy of the object.

 +==== Input ====
 +<code Quanty 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
