Comment
New rec. value and MACS vs. kT table is taken from recent evaluation (jendl40) which is the only one to include the most recent measurement from CDP07a. Uncertainty taken from CDP07a.

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
rRecalculated for kT = 30keV with the code described in Ref. 2 after renormalizing the original data to updated standard cross sections
2Including k from Ref. ABM82, where k is a correction factor which has been applied to the originally reported cross section
eEvaluated value taken directly from the reference
