.. py:class:: CartesianSiteMoments(moments, precision = None)

   Bases: :py:obj:`httk.atomistic.models.moments.backend.SiteMomentsBackend`


   Per-site Cartesian magnetic moments, exactly held in Bohr magnetons.


   .. py:attribute:: kind
      :value: 'cartesian'



   .. py:property:: cartesian_moments
      :type: httk.core.SurdVector


      The exact Nx3 Cartesian moments, one row per site.


   .. py:property:: precision
      :type: fractions.Fraction | None


      How precisely the moments were stated, in Bohr magnetons, or ``None``.

      Concrete rather than abstract, so a backend with no source of precision inherits
      ``None`` instead of breaking.
