TABLE 1. — Phases time range from 14C modeling in the cultural sequence of Doi Pha Kan site. See stratigraphic sketch for the location of dating. Data was calibrated and modeled in ChronoModel 3.1.8 (Lanos & Dufresne 2019), using IntCal20 calibration curve (Reimer et al. 2020). The starting and ending points of the posterior distribution are defined as the maximum a posteriori (MAP) of the phase distribution, in each case (fourth and fifth columns), at 95% confidence level. The phase time range (sixth column) is also given for a 95% confidence level.
