#COMENT       (a)f is electron screening enhancement factors.
#                Systematic uncertainties include 7Be counting efficiency(1.8%), Beam intensity(1.5%),
#                Beam heating effect(1.3%), Target pressure and temperature without beam(0.6%),
#                7Be backscattering(0.5%), Incomplete 7Be collection(0.4%), 7Be distribution in catcher
#                (0.4%), 478 keV gamma-ray branching(0.4%), Effective energy(0.5%-0.8%). 
#                Total 2.9%-3.0%.
#               S(0) is also shown in the text.
