Example of a signal in the light curve of TIC 64111698 with both S/N and SDE above our thresholds. The light curve was still ruled out during our visual inspection. The position of the two detected transits is suspicious (top panel): the first transit occurs is in a high-noise region, and the second transit is at the edge of a dataset, where typically more trends exist. The phase-folded light curve (middle panel) shows strong variability out of transit with a similar amplitude as the transit signal. Finally, the signal has no harmonics and does not significantly rise above the noise (bottom panel). All these hints suggest that the spotted signal is most likely a false positive.
