ALHAMBRA quiescent fraction f_Q in four redshift bins (labelled in the panels). The red dots are the observed f_Q. The red solid line is the quiescent faction median model, and the coloured area its 95% confidence range. The other symbols, labelled in the panels, are from the literature: the dashed lines are from the Schechter best fit of Faber et al. (2007), Zucca et al. (2009), and Fritz et al. (2014), the white pentagons are from Brown et al. (2007), the squares from Drory et al. (2009), and the diamonds from Salimbeni et al. (2008). The error bars mark 2σ confidence intervals. The dotted horizontal line marks f_Q = 0.5.
