_atom_site.occupancy

Definition:

   
     The fraction of the atom type present at this site.
     The sum of the occupancies of all the atom types at this site
     may not significantly exceed 1.0 unless it is a dummy site. The
     value must lie in the 99.97% Gaussian confidence interval
     -3u =< x =< 1 + 3u. The _enumeration.range of 0.0:1.0 is thus
     correctly interpreted as meaning (0.0 - 3u) =< x =< (1.0 + 3u).
