Description
We build two families of inspiral waveforms for precessing
binaries on eccentric orbits in the Fourier domain. To
achieve this, we use a small eccentricity expansion of the
waveform amplitudes in order to separate the periastron
precession timescale from the orbital timescale, and use a
SUA transformation to compute the Fourier transform
in the presence of spin-induced precession. We show that
the resulting waveforms can yield a median faithfulness
above $0.993$ when compared to an equivalent time domain
waveform with an initial eccentricity of $e_0 ≈ 0.3$. Using
a circular waveform can potentially lead to significant
biases in the recovery of the parameters, even when the
system has fully circularized. This is an effect of the
residual eccentricity present when the objects forming the
binary have non-vanishing spin components in the orbital
plane.
