.. include:: /substitutions.rst .. _fdoptimizationbeams: FD_Optimization_beams.pdf ========================= The FD_Optimization_beams.pdf file plots |IV| curves obtained from |R-factor| calculations during :ref:`full-dynamic optimization`. |IV| curves are drawn for every beam, showing theoretical curves at every data point tested during optimization, as well as the experimental data. The file format is generally equivalent to the one of the :ref:`Rfactorplots` files. Appearance of the |IV| plots can be modified with the :ref:`PLOT_IV` parameter. |R factor|\ s are between the *best* theoretical dataset (marked by the thicker line) and the experimental data.
