The gluon propagator has been calculated for quenched QCD in the
Landau gauge at
= 6.0 for volumes
163 x 48 and
323 x 64, and at
= 6.2 for volume
243 x 48. The
large volume and different lattice spacings allow us to identify and
minimise finite volume and finite lattice spacing artefacts. We also
study the tensor structure of the gluon propagator, confirming that it
obeys the lattice Landau gauge condition.
