Relationship between the quenching age QA (upper panel) and the quenching factor QF (lower panel) and the HI-deficiency parameter for objects with . Blue filled squares, green triangles, and red circles are for galaxies where the derived quenching factor is QF ≤ 0.5, 0.5 <QF ≤ 0.8, and QF> 0.8, respectively. The large black empty symbol shows the mean value and the distribution in HI-deficiency for galaxies with a QF ≤ 0.5 (for which the quenching factor and quenching age are arbitrarily set to QF = 0 and QA = 0.4 Myr). The dotted line in the lower panel indicates the best fit found by Ciesla et al. (2016).
