Comment
Recommended value is weighted average of CDP06b and MCA98. MACS vs. kT for kT=5-25 keV from CDP06b multiplied with 0.993, from kT=30-50 keV from MCA98 multiplied with 1.007, and from kT=60-100 keV previous values multiplied with 0.828.

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
rRecalculated for kT = 30keV with the code described in Ref. 2 after renormalizing the original data to updated standard cross sections
1Including k from Ref. MaW81, where k is a correction factor which has been applied to the originally reported cross section
eEvaluated value taken directly from the reference
