Partial c.s. to ground state:	2.23	±	0.07	mb

Cross sections do not include stellar enhancement factors!

0.2	2.56 ± 0.30	2.32 ± 0.14	-
0.0	2.70 ± 0.48	2.32 ± 0.14	-

(Version 0.0 corresponds to Bao et al.)

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>/v_T] (mb) for kT=30 keV, based on the published cross sections except where indicated otherwise.
Renorm:MACS [<σ v>/v_T] (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:

c	Directly quoted from the reference itself
r	Recalculated for kT = 30keV with the code described in Ref. 2 after renormalizing the original data to updated standard cross sections
1	Including k from Ref. MaW81, where k is a correction factor which has been applied to the originally reported cross section
e	Evaluated value taken directly from the reference
t	Theoretical value

MACS:
Reference: MCA98, CDP06b
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.)
