Notes. $\epsilon~_{\Sigma W}$ is the absolute semi-difference of the equivalent widths measured on the individual spectra. The listed metallicity values were calculated from $W^\prime$ using the quadratic calibration. The last two columns give the lower and upper confidence intervals of our age estimates (see text for details).
