= Central charge of reparameterization ghosts
{title2=$c_{\mathrm{gh}}=-26$}

The <worldsheet ghost fields> form a <bc system> with <conformal weights> $2$ and $-1$. Setting $J=2$ in $c=-2(6J^2-6J+1)$ gives <central charge> $-26$ in each chirality. The <worldsheet Weyl anomaly> of $D$ free embedding bosons cancels at $D=26$.
