Names:
'_restr_equal_torsion_atom_site_label_1' '_restr_equal_torsion_atom_site_label_2' '_restr_equal_torsion_atom_site_label_3' '_restr_equal_torsion_atom_site_label_4'

Definition:

   The atom-site labels of the four atoms that define one of the
   torsion angles restrained to be equal to other torsion
   angles in the same class.  The torsion angle is the dihedral
   angle between the plane defined by atoms 1, 2 and 3, and
   the plane defined by atoms 2, 3 and 4.
