! Results from the E155 NLO pQCD fits to the world data set of g1(x,Q^2).
! Beam energy: 48.35 GeV.

!
! a_3 and a_8 are the non-singlet matrix elements.
! Delta Sigma is the quarks contribution to the spin of the proton.
! Gamma_1^p is the integral of g1p for 0 < x < 1. The expressions
! for Gamma_1^n and Gamma_1^d are comparable.
! Gamma_1^{p-n} is the Bjorken Sum Rule.
