  The Coulomb gauge in QCD is the only explicitly unitary gauge. But it suffers
from energy-divergences which means that it is not rigorously well-defined. One
way to define it unambiguously is as the limit of a gauge interpolating between
the Landau gauge and the Coulomb gauge. This interpolating gauge is
characterised by a parameter theta and the Coulomb gauge is obtained in the
limit theta tends to zero. We study the renormalization of this theta-gauge for
all values of theta, and note some special features of it.
