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:
bCalculated from smooth cross sections with model fit: ln(sigma) = a + a1 ln(E) + a2 ln^2(E)
cDirectly quoted from the reference itself
1Including k from Ref. MaW81, where k is a correction factor which has been applied to the originally reported cross section
eEvaluated value taken directly from the reference

MACS:
Reference: MaW81,CVB83
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: 1983
