Query: Including mode mixing in a higher-multipole model for gravitational
  waveforms from nonspinning black-hole binaries   As gravitational-wave (GW) observations of binary black holes are becoming a
precision tool for physics and astronomy, several subdominant effects in the GW
signals need to be accurately modeled. Previous studies have shown that
neglecting subdominant modes in the GW templates causes an unacceptable loss in
detection efficiency and large systematic errors in the estimated parameters
for binaries with large mass ratios. Our recent work [Mehta et al., Phys. Rev.
D 96, 124010 (2017)] constructed a phenomenological gravitational waveform
family for nonspinning black-hole binaries that includes subdominant spherical
harmonic modes $(\ell = 2, m = \pm 1)$, $(\ell = 3, m = \pm 3)$, and $(\ell =
4, m = \pm 4)$ in addition to the dominant quadrupole mode, $(\ell = 2, m=\pm
2)$. In this article, we construct analytical models for the ($\ell = 3, m =
\pm 2$) and ($\ell = 4, m = \pm 3$) modes and include them in the existing
waveform family. Accurate modeling of these modes is complicated by the mixing
of multiple spheroidal harmonic modes. We develop a method for accurately
modeling the effect of mode mixing, thus producing an analytical waveform
family that has faithfulness >99.6%.
