Results for local clock models, MSS and HOPACH, are given both for the maximum a posteriori (MAP) tree and as a posterior probability weighted average over the 95% credibility set (CS) of topologies sampled from the appropriate target distribution. The uncorrelated models from BEAST (UCLN: uncorrelated lognormal) integrate over tree topologies, branch lengths and parameters of the substitution model. Times are in million years ago. SSD are computed with respect to UCLN (baseline).
