Notes. The uncertainties quoted above are calculated from the root mean square deviation from the mean of the values determined for individual stars within that cluster, except for Trumpler 5, where we only have one star in our sample. For this cluster, the listed uncertainties instead are representative estimates based on the mean uncertainties of the other clusters.
