Intensity-distribution effects of symmetry elements causing systematic absences

Abbreviations and orientation of axes: A = acentric distribution, C = centric distribution, Z = systematically zero, S = distribution parameter, 〈I〉 = average intensity. Axes are parallel to c, planes are perpendicular to c.
