Selected modeled calendar age ranges from the models and outputs shown in Figs 3–5.

TPQ refers to a date solely from a long-lived sample(s). Typical results shown; very small variations (often of around 1 year) occur between different model runs (we illustrate by giving results from a very similar but different model run in S3 File, where a number of start/end dates for some of the ranges are 1 year different). For comparison of the results for Model 2 with the previous IntCal13 [134], see below in Table 6. Whole ranges only are listed (compare with S3 File where sub-ranges are listed). The Time Span Phases 4&3 Date estimate combines the separate start (Phase 4) and end (Phase 3) Date estimates in the model.
