where $\phi$ and $\phi^\pm$ are the remaining components of the U(1) gauge field and the gravitino respectively, and $\sigma$ is the Liouville mode. The covariant combinations which reproduce  under a condition $\phi=\phi^\pm=0$ are $$\eqalign{

\eqn\twofortyseven$$ The above covariantizations are unique ones. Therefore if we take our definition of the BRST supercurrent , we have $$\partialbar\VEV{j_B(Z)}
  ={d-2\over4}\partialbar\VEV{C\left({1\over2}D^-\Phi D^+\Phi
                  +i\partial\Phi\right)}.
\eqn\twofortyeight$$ Here we should emphasize that the BRST anomaly in  vanishes for $d=2$. In the case of $N=0$ and $N=1$ (super-)gravity, on the other hand, even if one take a BRST invariant BRST current as in , the BRST anomaly contains a additional total divergent piece \[,\], which does not proportional to $d-26$ and $d-10$ respectively. As a consequence, the BRST anomaly in $N=0$ and $N=1$ (super-)gravity does [*not*]{} vanish even in the critical dimension $d=26$ and $d=10$. The origin of the total divergent BRST anomaly is the fact that the BRST invariant path integral measure is invariant under the global BRST transformation, up to a total divergence \[\]. Therefore it generates a total divergent anomaly in general under a [ *localized*]{} BRST transformation, like . In
