A reader a few months ago asked for a post when a PSCF paper by myself and Ken Wolgemuth became open source. The paper describes how we can combine independent data sets, such as carbon-14, tree rings, and annual lake deposits (varves), to put assumptions about the unobserved past to rigorous tests. The paper takes advantage of the highly detailed work researchers have done with sediment cores collected from Lake Suigetsu in Japan. The full paper can be freely accessed at the link below.
