Original:MACS [<σ v>/vT] (mb) for kT=30 keV, based on the published cross sections except where indicated otherwise.
Renorm:MACS [<σ v>/vT] (mb) for kT=30 keV for which the reference or standard cross section was meanwhile improved.
Type: The letters and numbers in the column labelled 'type' give information on how the cross section has been obtained:
cDirectly quoted from the reference itself
dRenormalized 2017 based on updated Au measurement
2Including k from Ref. ABM82, where k is a correction factor which has been applied to the originally reported cross section
eEvaluated value taken directly from the reference
sSemiempirical estimates given in the reference
