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 or broken at any time. On the other hand, they have more features than the stable versions. The stable versions appear on the main index page.

Version 3

Includes all commonly used nuclide-mineral pairs where production is dominantly by spallation (e.g., not Cl-36). New features include a different (better) input/output format for multiple-nuclide data, arbitrary paired-nuclide plots, a fast LSDn implementation, and summary stats on age data from a single landform.

All of version 3 should be stable for He-3 in pyroxene and olivine, Be-10 in quartz, and Al-26 in quartz. Development is ongoing for He-3 in quartz, Ne-21 in quartz, and C-14 in quartz.
