(a) Laboratory coordinate system and (b) object-coordinate system , which are related by the rotation matrix . In (a) the planar two-dimensional cut through the reciprocal-space map in the plane of the detector is illustrated in grey. The object-coordinate system defines the position of each voxel of the object. (c) In each voxel a series of spherical harmonics functions is used to describe the three-dimensional reciprocal-space map, from which the scattering signal can be obtained. The preferential orientation of the nanostructure in each voxel and each q is characterized by a unit vector defined by the polar and azimuthal angles.
