  The two-point function of linearized gravitons on de Sitter space is infrared
divergent in the standard transverse traceless synchronous gauge defined by
$k=0$ cosmological coordinates (also called conformal or Poincare coordinates).
We show that this divergence can be removed by adding a linearized
diffeomorphism to each mode function; i.e., by an explicit change of gauge. It
follows that the graviton vacuum state is well-defined and de Sitter invariant
in agreement with various earlier arguments.
