IOSA Radiocarbon Calibration Service

Radiocarbon calibration, HTTP style


This web app is the demo service for the IOSA Radiocarbon Calibration Library (IOSACal), an open source radiocarbon calibration program and programming library. The web app itself is open source.


IOSACal is written in the Python programming language and is based on Numpy, Scipy and Matplotlib. This work wouldn't be possible without the availability of such high quality programming libraries.

The web app is made with Flask and the Bootstrap framework.

Data sources

The random radiocarbon dates are retrieved from the Mediterranean Radiocarbon dates database on GitHub.
