Original:MACS [<σ v>/v_T] (mb) for kT=30 keV, based on the published cross sections except where indicated otherwise.
Renorm:MACS [<σ v>/v_T] (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:

r	Recalculated for kT = 30keV with the code described in Ref. 2 after renormalizing the original data to updated standard cross sections
c	Directly quoted from the reference itself
2	Including k from Ref. ABM82, where k is a correction factor which has been applied to the originally reported cross section
e	Evaluated value taken directly from the reference
t	Theoretical value

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.)
