Standard deviations of the integrated depths for different window lengths (dotted and dashed curves) and the integrated depths of different-size windows centered at the midtime of the candidate transit event (color points). The integrated depths peak at the time lengths of 76, 78, and 80 minutes, which are close to the transit duration, in our grid of GP analysis. These three windows contains the same photometric data points, thus they are identical. That window matches the candidate transit event in midtime and length. Its integrated depth is over the 2.5σ threshold in both the Matérn 3/2 GP model and Squared Exponential GP model cases.
