POLARIZATION

    Useful
    x y z

This card specifies the direction of the electric field of the incident beam, or the main axis of the ellipse, in the case of elliptical polarization. x, y, z are the coordinates of the nonzero polarization vector. The ELLIPTICITY card is not needed for linear polarization. If the POLARIZATION card is omitted, spherically averaged XAFS will be calculated.

Note that polarization reduces the degeneracy of the paths, increasing the calculation time. Choosing polarization in the directions of symmetry axes will result in a faster calculation.
