Example of the detrending procedure for target EPIC 212035051 in campaign 5. The improvement in the flux standard deviation is from 0.008 for the raw light curve to 0.004 for the detrended light curve. Top: raw flux. Middle: time-correlated component, mostly quasiperiodic stellar variability, with pointing drift noise removed. Bottom: detrended light curve on which we perform the transit search. Red points are outliers at more than 3 standard deviations from the trend. They are masked out during the detrending; i.e. we do not use them to predict the noise trend.
