   characteristic squared amplitude
      The characteristic squared amplitude, :math:`|| h^{2} ||`, is defined as
      
      .. math::
	 
	 || h^{2} || = \int_{\infty}^{\infty} | h(t)|^{2} \dd{t} =  \int_{\infty}^{\infty} | \tilde{h}(f) |^{2} \dd{f},
	 
      for :math:`h(t)` and :math:`\tilde{h}(f)` respectively the strain in the time, :math:`t`, and frequency :math:`f` representations :cite:`2008CQGra..25d5002B`.
