Here we investigate ... Netteta wiggle-match between 14C ages of decadal blocks and the IntCal13 calibration curve (Reimer et al. 2013), although the same 14C data favor a felling date in the AD 830s when wiggle-matched to IntCal20 (Reimer et al. 2024). Our results appear to confirm doubts expressed by Philippsen et al. (2024) about IntCal20 values from ca. AD 825-835.
