Notes. The meaning of the columns are, from left to right: cluster name, total number of members, number of members used in age determination, median parallax of the cluster in mas, standard deviation of the parallax in mas, the median isochronal age of the cluster in Myr, the uncertainty of the age in Myr, the estimated extinction AV in mag, and the uncertainty of AV in mag.
