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

MACS:
Reference: HKW98
Procedure: 'e' (The Maxwellian-averaged cross sections (MACS) from kT=5 keV to 100 keV are obtained from experimental data; the relative uncertainties are similar to those quoted for the 30 keV data.)
Year: 1998

SEF (Stellar enhancement factor):
Reference: Rau09
Year: 2009
Comment:
. Please note: SEF for this element have not been calculated but are expected to be close to 1.
Rate:
