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:
aCalculated from resonance parameters with the formula from Ref. 45
1Including k from Ref. MaW81, where k is a correction factor which has been applied to the originally reported cross section
