Development versions

Developmental versions: These versions are in active development, are very likely to contain errors, may not work at all, and may be offline for changes at any time. On the other hand, they have more features than the stable versions. The only reason to use these is if you're participating in the development or if you want to use a particular feature that's not in the stable versions. The stable versions appear on the main index page.

Compute exposure ages with alternative calibration data sets
These pages work just like the default input page for calculating exposure ages using the version 2.2 code, but use alternative calibration data sets. Some of these calibration data sets are documented in publications, and the references are listed on the respective pages. Calibration data sets that have no published reference associated with them are preliminary or trial data of some sort and I'm unable to provide detailed documentation -- you are on your own if you want to use them.

New Zealand calibration (A. Putnam et al., in review)

10Be production rate calibration -- in development
This gives the option to generate reference 10Be production rates from calibration data sets of your choice rather than using the default production rate calibration data set. This page allows you to enter calibration data, and returns a new page that i) shows the results of the calibration, and ii) allows you to compute exposure ages using your calibration.
Establish a production rate calibration

36Cl - development:
Proto-Cl-36 calculator from 2002
(Not at all updated. Doesn't do much. Almost manages to calculate the complete production/depth profile. Uses an interesting numerical diffusion scheme.)
