_category.description           
;              Data items in the ATOM_SITE category record details about
               the atom sites in a macromolecular crystal structure, such as
               the positional coordinates, atomic displacement parameters,
               magnetic moments and directions.

               The data items for describing anisotropic atomic
               displacement factors are only used if the corresponding items
               are not given in the ATOM_SITE_ANISOTROP category.
