Upper panel: distribution of the relative difference between the estimated and true age of the old stellar population. The sample is split as a function of the true age: tf = 1 Gyr, tf = 2 Gyr, tf = 3 Gyr, and tf = 4, 5 Gyr. Lower panel: distribution of the ratio of the estimated and true age of the young stellar population in logarithmic units. The sample is split as a function of the true age: tySP = 0.01 Gyr, tySP = 0.03 Gyr, tySP = 0.1 Gyr, and tySP = 0.3 Gyr.
