Name:
`'_array_structure_list_axis.angular_pitch'`

Definition:

            The pixel-centre-to-pixel-centre distance for a one-step
                   change in the setting of the specified axis in millimetres.

                   This is meaningful only for 'constant velocity' spiral scans
                   or for uncoupled angular scans at a constant radius
                   (cylindrical scans) and should not be specified for cases
                   in which the angle between pixels (rather than the distance
                   between pixels) is uniform.

                   See _array_structure_list_axis.angle_increment.
