Introduction and overall purpose

Mailing list:

We maintain a mailing list intended to notify users of the cosmogenic-nuclide calculators about changes, updates, or newly discovered bugs. We don't anticipate that there'll be very much traffic on this list, but we strongly suggest that users subscribe to it so that they'll be quickly notified of any errors that we might discover.

Information on AMS measurement standards

Description of how to compute nuclide concentrations from isotope ratio measurements: PDF HTML

This document gives instructions on how to a) reduce the isotope ratios actually reported by an AMS lab to the nuclide concentrations in quartz that are required for the exposure age/erosion rate calculators, and b) account for carrier and process blank uncertainty.

DRAFT Paper describing the calculation methods: PDF

This describes Version 1. For basic information about the inner workings, goals, assumptions, and limitations of the calculators, read this first. Note that this draft describes Version 1 only.

DRAFT MATLAB function reference for Version 1: PDF

DRAFT Geological calibration data set for Version 1: Excel spreadsheet

Direct access to MATLAB code for Version 1.
