Example of the GP modeling for a single source. Top: time series photometry for this star; red shades denote the confidence intervals for the GP model, shaded black line denotes the median trend with corresponding confidence interval in gray. Gray and black points are masked and accepted points, respectively. Bottom panels: phased light curves for the star without (left) and with (right) the median trend correction applied. Colored regions are the confidence intervals for the Fourier fit.
