Ratio of the fraction of star-forming (F_SFing) to blue (F_blue) galaxies in the mass limited sample in the three redshift bins and in different global (top) and local (bottom) environments. Dashed lines in the top panel show trends when AGNs are removed form the sample as explained in the Appendix B. In both panels, error bars are computed by propagating the asymmetric errors on the single fractions by means of the statistical error propagation.
