Removing radius and volume units from the covector fit step

  2. theorem OAI.RegularPointCoordinates.radial_covector_fit_natural_units line 20

    Source documentation

    The actual covector error has one coefficient independent of the center and dyadic scale; its only variable source is sqrt(P) times the norm of the covector in the current normalizing frame.
