Ratio of the fitted sky level to the flux of the star as a function of color, for high flux stars only in i band. For such stars we assume that the fitted sky level is predominantly a fraction of the flux incorrectly fitted as the sky level. We see that the fraction of flux that goes into our sky level estimator evolves linearly with color.
