Anomalous scattering factor f1/f2 calculations and mirror reflectivity.

Functions

f1f2_calc(descriptor, energy[, theta, F, ...])	calculate the elastic Photon-Atom anonalous f1 and f2 coefficients as a function of energy.
f1f2_calc_mix(descriptor, energy[, theta, ...])	Like f1f2_calc but for a chemical formula.
f1f2_calc_nist(descriptor, energy[, theta, ...])	Like f1f2_calc but for a compound defined in the NIST list
