WinPLOTR demo. 3:
Automatic Profile Fitting Procedure
This example demonstration will show the procedure to fit automatically peaks profile
in a particular range of a diffraction pattern. This profile fitting procedure
uses pseudo-Voigt functions with a global FWHM (Full Width at Half Maximum) and
a global eta (lorentzian proportion), and a linear background. Each peak is then
characterized by its angular position, intensity, FWHM and eta shifts with respect
to the global parents.
The data file in this example corresponds to a neutron diffraction pattern of
a powdered garnet (Tb3Fe5O12), recorded at room temperature on G42 High Resolution
Multicounters Powder Diffractometer at LLB (l = 2.3433 A).
