The cluster was compared to its upstream U106 age estimates which run, if I
remember correctly, closer to 4000 years.
L48 would the intermediate I guess, but again we're going to get into the
statistical uncertainties for the closer ages. As we increasingly try to
make age estimates within the more bushy parts of the y tree, it will be
more and more difficult to get meaningful age differences for the closely
