Left: distributions of estimated ages for stars of given true ages marked by the vertical red lines in the individual panels. Values of the true age, as well as the percentage difference and standard deviation, are marked. Right: same as left, but for distributions of true ages for stars of estimated ages in a limited (±0.25) range.
