First three iterations of the apodized sine periodograms (ASPs) method. Models correspond to the maximum of the ASPs. T_obs designates the timespan between the first and last RV observation, and τ has the same meaning as in Eq. (1). The left panels represent the periodograms, the middle panels show a zoom in on the highest peak, and the right-hand panels represent a statistical significance test (see Hara et al. 2022, for details). We note that the best fitting τ for the 26 d signal is not the longest. We attribute this to the sequential fitting. In the first iteration, the 69 d signal is not removed. Because there are only 49 RV measurements, the aliasing is strong, and the presence of the 69 d signal in the first iteration creates interferences. If we first remove the 69 d signal, the longest timescale has the same statistical significance as τ/T_obs = 3.
