Notes. Columns 2−4 give the maximum-likelihood estimates of the age, mass, and initial metallicity, respectively. Column 5 is the chi-squared statistic of the fit for the parameter values in Cols. 2−4. Columns 6 and 7 give the mean and standard deviation of their posterior distributions. The systematic errors on the mass and age due to uncertainties in the mixing length and helium abundance are given in Cols. 8 to 11.
