Comment
New rec. value is taken from WBC15 which is in perfect agreement with the previously measured values from CL13 but has a much smaller statistical and systematical uncertainty. The given statistical and systematical uncertainties are added linearly.

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:
