Pekowsky Test Precessing IMR

Several groups are attempting to construct synthetic gravitational wave signals that include the effect of precessing

—— FINISH ME —-

For experts: Each corotating-frame mode resembles the corresponding mode from a nonprecessing source. Hence, you can generate artificial precessing waveforms: view a nonprecessing source along a time-dependent direction. The resemblence is superficial, since this procedure can’t capture all of the physics. But, as a kludge, how well do those synthetic waveforms do?

              Rather than compare all possible lines of sight of the synthetic and real precessing system, we
              instead compare them in the corotating frame.  If similar, then the synthetic waveforms
              must be similar.
