If the gauge fixing favors Gribov copies with small \\lambda_1 the ghost dressing function rises more rapidly towards zero momentum than on copies with large \\lambda_1. This effect is seen for momenta below 1 GeV, and interestingly also for the gluon propagator at momenta below 0.2 GeV: For large \\lambda_1 the gluon propagator levels out to a lower value at zero momentum than for small \\lambda_1.
