Warning or Documentation about default form factors throughout the entire photon energy range

[EmCeBeh]

By default atoms use the chantler tables for form factors. These are usually superiror to Henke tables in the (Soft) X-ray range above the water window, but in the XUV range in the lower hundrets of eV the Henke tables seem to show better resolution (e.g. Gd, Fe, and Si). Maybe one could combine them in a useful way to ChantlerHenke for a continous coverage.

many thanks for that hint.
I was thinking of adding a udkm1Dsim_config.default file where users can set their default source including a short explaination.
In addition a more detailed documentation for the according methods like get_atomic_form_factor etc would be helpful as well.

One could also think of an automatic ways of chosing the right tables depending on the photon energy, but I guess this is not so easy for all the diferent elements.
