While trying to plot the values of anomalous scattering factors f' and f'' in the energy range from 10 eV to 30 keV, I noticed some local instabilities in the output data of functions Fi and Fii (please refer to attached graphs). These anomalies fluctuate by several orders of magnitudes, but the overall shape of the curve agrees well with the Henke data.
For example,
Fi(14, 105.030000e-3)
returns -896.729846725145, while Henke data for this energy is -2.04570.
I wonder this issue is due to the inherent anomalies in Kissel data?
