Current stable versions: These reflect the calculation methods and calibration data described in a 2008 paper with numerous updates. Use
these unless you have a particular reason to use the developmental or archived versions.
For some context about the various versions, see this.

Calculate topographic shielding

The version 3 family is stable for He-3 in pyroxene and olivine and Be-10, Al-26, Ne-21, and C-14 in quartz. Calculations
for He-3 in quartz are available but subject to further development.

The previous stable version is 2.3. The version 2.3 exposure age and erosion rate calculators are still available on the archive page,
but will no longer be supported. Production rate calibration using version 2.3 is no longer available.

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 might have more
features than the stable versions.
They appear on a separate page.
|
|
|
Archived versions: These have been superseded by
the current stable version, but they are archived here so that calculations done in the past can be reproduced.
They appear on a separate page.

"You do the excavation...we do the computation."
It's the OC. Since 2006.
