Input (dark blue) and output (all stars: light blue; M stars: black) age distributions for exact-distance (left) and inexact-distance (right) analyses. The mean and median for the F (M) stars are shown as solid and dotted red (black) vertical lines, respectively. In the exact-distance case, the average F star age is 10.4 Myr with an rms of 2.2 Myr, and the average M age is 7.0 Myr with an rms of 4.3 Myr. In the inexact case, the F age is 10.5 Myr with an rms of 3.5 Myr, and the M age is 7.5 Myr with an rms of 5.8 Myr. Binary M stars produce a young peak in both scenarios, biasing the apparent mean age to younger values than those for F stars. The bimodality of the M star distribution in the exact-distance analysis is somewhat smoothed in the inexact-distance analysis, where incorrect distances create more heterogeneity in the measured population ages.
