IntCal20: The IntCal20 northern hemisphere radiocarbon curve for the 0-55,000 yr BP period

Description

Atmospheric radiocarbon calibration curve for the period 0 to 55,000 yr BP for the northern hemosphere. This is the most recent update to the internationally agreed calibration curve and supersedes IntCal13.

Usage
