EELS curve fitting
==================

Performs curve fitting to an EELS spectrum, plots the result and saves it as
png file.

Create a model and fit it to the data.

.. note::

   By default, :ref:`generalized oscillator strength (GOS) <eels.GOS>` calculated using density functional theory (DFT)
   are used. Use the ``GOS`` parameter to change to use other GOS, for example ``GOS="dirac"``.
