Apodized sine periodogram of the RV data, including offsets, transiting planets, and order 11 polynomial in the base model. Left: apodized periodogram for different apodization timescales, that is Eq. (E.1) for τ = 10T_obs (blue), T_obs/3 (orange), T_obs/9 (green) and T_obs/27 (red), denoting by T_obs the observation timespan of the data. Horizontal dashed lines represent the value of the ASP at the period corresponding to the global maximum (here attained for τ = T_obs/3 Middle: zoom around the maximum peak. The right panel represents a statistical test: assuming the true value of the timescale given in the x axis, the circles represent the expected value of the peaks corresponding to other timescales, the error bar represent the standard deviation. For instance, assuming τ = 10T_obs is the true timescale, we would expect an apodized sine with τ = T_obs/3 to have a χ² difference of ≈ 12 ±5, which is 5.4 σ away from the measured value (39, orange dashe line). The error bars are horizontally shifted to improve the readability of the figure, but they correspond to the same assumed timescale.
