there are several types of radiocarbon methods already in SEAD:|

  • method_id: method_name
  • 156: Calibrated radiocarbon date (method unspecified)
  • 157: Calibrated AMS radiocarbon date
  • 149: Radiometric date by unknown method

The first draft of data mapping will use 157, until and unless I receive information suggesting I choose another
