Ratio of the number of active over passive galaxies (f_ap) in VIPERS real data (orange and violet symbols) and in the Rmocks (filled rectangles and diamonds). The points for the Rmocks are the same as in Fig. 6. The points for the VIPERS sample are taken from Fig. 5, but for the sake of simplicity, in each mass bin for the environment with more galaxies (LD for log (ℳ/ℳ_⊙) < 11.29, HD otherwise) we plot only f_ap as derived from the mass-matched samples, instead of also plotting the original value as in Fig. 5.
