  We report on the infrared limit of the quenched lattice Landau gauge gluon
propagator computed from large asymmetric lattices. In particular, the
compatibility of the pure power law infrared solution $(q^2)^{2\kappa}$ of the
Dyson-Schwinger equations is investigated and the exponent $\kappa$ is
measured. Some results for the ghost propagator and for the running coupling
constant will also be shown.
