Quadrupole difference tolerance. The distributions of the 3-D neighbors as a function of the binned quadrupole differences, 
, of the two moleclues in each neighbor for (
, 
) = (100, 110), (100, 120), and (100, 130), respectively, illustrating how the frequency of ΔQbin rapidly decreases to zero as a function of magnitude.
