SharedGeometry.shared_frame_data
================================

.. py:method:: t3toolbox.shared_geometry.SharedGeometry.shared_frame_data(frame)

   .. code-block:: python

      def shared_frame_data(self, frame) -> backend_sharing.SharedFrameData:


   The per-frame companion (centers + the stacked-``S`` SVD), derived from ``frame``
   (a ``T3Frame`` or a ``UT3Frame``).

   ``svd_s`` is the group spectrum ``s_g`` -- the continuation/aptness statistic, free at
   every frame. Manifold bases only (the corewise post-pass needs no companion).
