Comment
Rec. value is from WVK95. MACS values at kT= 5-10 keV were normalized to the average of the evaluated libraries (endfb71,jendl40), uncertainty is 2.5% as in WVK95 plus deviation of both libraries.

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:
dRenormalized 2017 based on updated Au measurement
cDirectly quoted from the reference itself
eEvaluated value taken directly from the reference
tTheoretical value
sSemiempirical estimates given in the reference
