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
eEvaluated value taken directly from the reference

MACS:
Reference: WGV93
Procedure: 'e' (The Maxwellian-averaged cross sections (MACS) from kT=5 keV to 100 keV are obtained from experimental data; the relative uncertainties are similar to those quoted for the 30 keV data.)
Year: 1993
