Base class to store a pole figure (PF) computation.

A pole figure is the X-ray diffraction intensity for specific integrated peaks for a hemispherical illumination of a real or virtual specimen.

Symbols:

n_y: Number of pixel per pole figure in the slow direction.

n_x: Number of pixel per pole figure in the fast direction.
