Pysochron 2

June 10, 2026

Pysochron 2 is an open source 26Al/10Be burial isochron calculator, available for download in both .exe and .py formats. Like the original Pysochron, it uses orthogonal distance regression to fit isochron lines to measured concentrations of 26Al and 10Be and accounts for uncertainty using a Monte Carlo framework. The final output is a .pdf that contains the burial isochron diagram along with a comprehensive table of settings, constants, and modeled results.
