Notes. In the model name, σjit refers to a jitter term added in quadrature to the RV error bars and “2 Sin” refers to two sinusoidal functions and their periods. All models assume circular orbits, and the amplitudes are given with their 1σ uncertainty. The 99.7 percentile of the Keplerian amplitude is provided in parenthesis. The result in bold indicates our adopted RV model.
