Fig. A.3
Left panels: distribution of the quenching age parameter QA(vel) for galaxies with 
and a quenching factor 0.5 < QF(vel) ≤ 0.8 (upper panel) and QF(vel) > 0.8 (lower panel) derived using a truncated star formation history (Eq. (4)) with the rotational velocity as a free parameter. The magenta histogram shows early-type galaxies, the empty histogram all late-type galaxies, and the black shaded histogram the HI-deficient (HI−def > 0.4) late-type systems. Right panels: the same distributions derived using a smoothly declining star formation history (Eq. A.1) and a fixed rotational velocity.
