Comment
Rec. value is the renormalized value from Rap02. New MACS vs. kT table is the normalized energy dependency from tendl15 and endfb71/jendl40. Uncertainty towards kT=5 and 100 keV is the extrapolated uncertainty from the deviation between the 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:

MACS:
Reference: Rap02, tendl15, endfb71/jendl40
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.)
