      Parameters
      ----------
      frame_i : `~gala.potential.StaticFrame`
      frame_r : `~gala.potential.ConstantRotatingFrame`
      w : `~gala.dynamics.PhaseSpacePosition`, `~gala.dynamics.Orbit`
      t : quantity_like (optional)
          Required if input coordinates are just a phase-space position.
  
      Returns
      -------
      pos : `~astropy.units.Quantity`
          Position in static, inertial frame.
      vel : `~astropy.units.Quantity`
          Velocity in static, inertial frame.
