Examples of PDFs of ager of observed galaxies at z = 0.55; different values of Dn4000 = [1.1, 1.3, 1.5] (from left to right), and S/NI, obs = 10 (upper panels) and S/NI, obs = 30 (bottom panels) are shown. Probability density functions are retrieved using only optical indices (red distributions) and both ultraviolet and optical indices (blue distributions). The blue shaded region represents the confidence interval corresponding to the 16–84 per cent percentile range of the PDF. The solid green line corresponds to the true value of ager = 4.31 Gyr, ager = 4.44 Gyr, and ager = 3.94 Gyr, respectively; the dashed vertical red (blue) line indicates the median value of the corresponding distribution.
