Comment
The new recommended value is the average from the recent evaluations (endfb71/jendl40/jeff32 and tendl15), the uncertainty is from covariance data in endfb71.
Warning! Data from MAB76d was re-calculated in WiM87 and a large discrepancy was found. However, endfb71, jendl40, jeff32 still favor the data from MAB76d, but tendl15 uses recalculated data from WiM87. New measurement needed!

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
bCalculated from smooth cross sections with model fit: ln(sigma) = a + a1 ln(E) + a2 ln^2(E)
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

MACS:
Reference: endfb71/jendl40/jeff32 and tendl15
Procedure: 'e+t' (The MACS from kT=5 keV to 100 keV are derived from calculated cross sections, which are then normalized to experimental data, e.g. to the values at kT=25 keV obtained in activation measurements. In these cases the uncertainties should be linearly increased below 25 and above 30 keV to reach about 30% at the extreme kT values.)
