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:

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
s	Semiempirical estimates given in the reference
t	Theoretical value
