Cross sections do not include stellar enhancement factors!

Version	Total MACS [mb]	Partial to gs [mb]	Partial to isomer [mb]
1.0	4.13 ± 0.20	-	-
0.0	4.00 ± 0.20	-	-

(Version 0.0 corresponds to Bao et al.)

New rec. value is weighted average of BCM97 and BeK80. MACS vs. kT table is normalized table from BCM97 but value at kT= 5 keV normalized to value from HDJ05.

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
2	Including k from Ref. ABM82, 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
