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:
rRecalculated for kT = 30keV with the code described in Ref. 2 after renormalizing the original data to updated standard cross sections
eEvaluated value taken directly from the reference
