Item _atom_site.U_equiv_geom_mean

Description

              Equivalent isotropic atomic displacement parameter, U~equiv~,
               in angstroms squared, calculated as the geometric mean of
               the anisotropic atomic displacement parameters.

               U~equiv~ = (U~i~ U~j~ U~k~)^1/3^

               U~n~ = the principal components of the orthogonalised U~ij~
