Flare candidate detection in the light curve of star KIC 10011070 observed in quarter Q = 4. Top panel: original light curve (blue dots) and running mean (red line) calculated with a boxcar function averaging over 15 cadences. The vertical dashed lines indicate a period around a potential flare. Middle panel: zoom-in on the period around the flare candidate indicated in the top panel. The running mean is shown as a solid red line and the running 5σ threshold as a dash-dotted orange line. Bottom panel: detrended time series obtained by subtracting the running mean and normalizing by the standard deviation σ. The three consecutive data points in the middle clearly exceed the 5σ threshold.
