Age (left) and mass (right) distribution of known members (top panels) and new members (bottom panels) from different subclusters. We have included those known members that do not belong to any subcluster and those that belong to one more subcluster (labeled as others “O” in the legend). Some new members belong to two subclusters, marked as “B/E”. Objects with ages 20 Myr and over are all included in the last bin.
