Classes

asp(energies, coefs[, orders])

Atomic scattering polynomial.

asp_abstract()

Abstract class for a piecewise polynomial representation of atomic scattering factors.

asp_complex(re, im[, truncate])

Container for a combined pair (real & imaginary) of atomic scattering polynomials.

asp_im(energies, coefs[, orders])

Identical to asp, but reserved for the imaginary component of the atomic scattering.

asp_re(energies, coefs[, orders])

Identical to the asp class, but reserved for the real component.
