Comment
Recommended value is weighted average (best representation method) of Koe01 and WVK96. MACS vs. kT table from average of recent evaluations (endfb71,jendl40) normalized by f=0.96 to the rec. value. Isomeric ratio at kT= 30 keV is IR=0.014.

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