Gravitational-wave signals from binaries that contain spinning black holes in general include an asymmetry between the $+m$ and $-m$ multipoles that is not included in most signal models used in LIGO-Virgo-KAGRA (LVK) analysis to date. This asymmetry manifests itself in out-of-plane recoil of the final black hole and its inclusion in signal models is necessary both to measure this recoil, but also to accurately measure the full spin information of each black hole. We present the first model of the anti-symmetric contribution to the dominant co-precessing-frame signal multipole throughout inspiral, merger and ringdown. We model the anti-symmetric contribution in the frequency domain, and take advantage of the approximations that the anti-symmetric amplitude can be modelled as a ratio of the (already modelled) symmetric amplitude, and analytic relationships between the symmetric and anti-symmetric phases during the inspiral and ringdown. The model is tuned to single-spin numerical-relativity simulations up to ... : 14 pages, 14 figures ...
