IN ORDER TO ACCOMMODATE THE PERFECT 50-50 MIXTURE, RECIPROCAL RELATIONSHIP OF THE AZYMETRIC HETERODIMER PRESENT IN THE CRYSTALLOGRAPHIC ASYMMETRIC UNIT, TWO POSSIBLE HETERODIMER PAIRS, EACH WITH 0.5 ATOMIC OCCUPANCIES, WERE MODELED. FOR EXAMPLE, THE OCCUPANCY OF MOLECULE A CAN BE EQUALLY BE DESCRIBED BY MOLECULE B AND VICE VERSA.
