Parameters of two solutions of the QCD fit. The assumed functional form at $Q^2_0 = 1 ($GeV$/c)^2$ is $q(x) = \eta x^\alpha (1-x)^\beta (1 + \gamma x)/N$ where N is the normalisation. The parametrisation is used for the singlet and gluon helicity distribution and the two non-singlet distributions $\Delta q_3$ and $\Delta q_8$.
