Definition:

   
     This loop provides a list of centering translations in an
     OG(k)-supercell description of a magnetic space group.
     For an OG(k)-supercell description, this loop is mandatory and
     entirely distinct  from the optional
     SPACE_GROUP_SYMOP_MAGN_CENTERING loop used to simplify the
     presentation of a BNS-supercell description.
     An integer translation in an OG setting of a type-4 magnetic
     space group may have  a time-reversal component of -1, in which
     case it is actually an anti-translation vector rather than a lattice
     vector.   This loop should include all centering and anti-centering
     translations, but does not include the time-reversal components,
     which are instead determined
     using the value of the _space_group_magn.OG_wavevector_kxkykz tag.
     Because the centering translations are listed in a separate loop
     in the OG(k) description,
     only representative point operations remain in the main
     SPACE_GROUP_SYMOP_MAGN_OPERATION loop.

Category is of type Loop
