def _smooth_interpolated_smooth(self):
smoothed_results = smoother.perform_smooth(self.x,<EOL>self.smooth_result,<EOL>TWEETER_SPAN)<EOL>self.smooth_result = smoothed_results.smooth_result<EOL>
Smooth interpolated results with tweeter span.

A final step of the supersmoother is to smooth the interpolated values with
the tweeter span. This is done in Breiman's supsmu.f but is not explicitly
discussed in the publication. This step is necessary to match
the FORTRAN version perfectly.
