Caption: Figure 8.

Histograms of the values of the light time series of Kepler-91. In gray is the flux time series as extracted from the observed data. In purple are the residuals of the flux time series with a mean noise model removed. The residuals have a much lower scatter than the original data. The standard deviation of the original data is 398 ppm while the standard deviation of the residuals is 166 ppm.
