To obtain a calendar age for the sample, this radiocarbon age needs to be compared against samples of known age by means of a calibration curve using a specially designed computer software application.This application uses a terrestrial calibration curve to calculate the calendar age.It is during this stage that the carbon present in the sample is converted into carbon dioxide.The carbon dioxide is collected and bubbled through various chemicals in the line, which purify it, and the amount of carbon dioxide that has been collected is measured.The moa bone analysis gave a radiocarbon date of 580 plus or minus 40 years.Using the terrestrial calibration curve, a calendar age of AD 1390–1435 was established for the moa bone sample.
