  "Description": "The IntCal20 radiocarbon calibration curves (Reimer et al.\n2020 <doi:10.1017/RDC.2020.68>) are provided as a data package,\ntogether with previous IntCal curves (IntCal13, IntCal09,\nIntCal04, IntCal98), other curves (e.g., NOTCal04 [van der\nPlicht et al. 2004], Arnold & Libby 1951, Stuiver & Suess 1966,\nPearson & Stuiver 1986) and postbomb curves. Also provided are\nfunctions to copy the curves into memory, and to read, query\nand plot the data underlying the IntCal20 curves.",
