Significance of detection of the TOI-1759 b orbit RV signal at 18.85 d in the SBGLSP analysis. Each curve represents the S/N as a function of the number of observations. The S/N is calculated as the ratio between the SBGLSP power at 18.85 d and the noise in the periodogram. There is a monotonic increase in the S/N with the number of observations for all data sets, showing the coherent nature of the signal detected.
