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:
Procedure: 't' (The MACS from kT=5 keV to 100 keV are obtained from theoretical calculations with corresponding uncertainties between 25 and 50% in most cases.)
Year: 2000

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:
