We have calculated #948;g/g in the nucleon at all measured kinematics. The smallness of #948;g/g in the measured kinematics should not be interpreted as the the gluon contribution to the nucleon spin is small. In fact the first moment of gluon polarization in the nucleon, #916;g(Q2) can be sizable.
