Raw flux (left panel) and detrended flux (right panel) of the 3rd quarter of LC #9 of the sample of active stars with an injected transit signal with P_orb = 12.60 days and R_p/R_*=0.056. Data-points are shown in black, whereas different colors represent the photometric variability model inferred from algorithm: Median (red), biweight with a window-size of 0.25 days (dark blue) and 1.0 day (light blue), Huber spline (green) and Lowess (orange).
