Hδ_A as a function of D4000_n for different redshift and stellar mass bins obtained for VIPERS stacked spectra. Error bars were obtained on the basis of Monte Carlo simulations. Values of Hδ_A for SDSS passive red galaxies obtained from the linear fit of Hδ_A-stellar mass relation for median stellar mass bins. D4000_n values were obtained in an analogous way. Error bars were derived from the uncertainties of the linear fits. The spectral feature strength expected for galaxies with stellar mass corresponding to the transition mass at which the mass functions of the star-forming and quiescent galaxy populations cross is indicated with blue, black, and red ellipses at z ~ 0.1, z ~ 0.7, z ~ 1, respectively. The error bars of the estimated spectral features for transition masses correspond to the areas of ellipses.
