Comment
Rec. value is from HKU08 renormalized by f= 1.0785 (632 mb/586 mb) due to corrected Gold cross section from RaK88 for activations. Using energy dependence from jendl40. Uncertainties at kT= 25 keV from HKU08, for extrapolation additional uncertainty in MACS vs. kT table due to covariance data from jendl40.

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:
rRecalculated for kT = 30keV with the code described in Ref. 2 after renormalizing the original data to updated standard cross sections
cDirectly quoted from the reference itself
eEvaluated value taken directly from the reference
