`emin emax estep`

To calculate ehe x-ray scattering factor far from the edge
(only the atomic part). The energy grid is regular in energy with `estep`
between `emin` and `emax`. This is typically needed to find
the contributions from edges other than those calculated with the DANES card.
Later it may be automated.
The total scattering amplitude is

In the dipole approximation and do not depend on , but
this is not true with quadrupole transitions added. This is currently neglected
and

is also tabulated in ``fpf0.dat`';
is printed out by FPRIME and can be used to obtain the total .
The total energy correction to is given in the first line of
``fpf0.dat`' in Cromer-Liberman, and the more accurate Kissel-Pratt
form. See our paper on elastic scattering amplitude for references and
details.
