Includes production due to spallation on Ca, K, Fe, Ti, secondary spallogenic neutron capture on 35Cl, and supported radioactive-decay-produced neutrons on 35Cl.
Does not yet include production from fast muons or negative muon
capture. Does not include paleomagnetic corrections. Some question as
to how we're gonna deal with erosion rates in light of our numerical
model for neutron capture. No error propagation yet. Many other
