Schematic of the model for the recording probability r(t), expressed as a deterministic function of (u,v), where v=(v1,…,v m ). The internal knot locations v1,…,v m are treated as uncertain, and augmented with additional knots at known locations a=1000, b0=1980, and b=2015. See the “Results” section for our choice of b0, and (4) in the Appendix for more details
