Renault's $j$-map for Fell bundle $C^{\ast }$-algebras

If $p\text{\hspace{0.17em}⁣}:\mathcal{B}\to G$ is a Fell bundle over an 'etale groupoid, then we show that there is an norm reducing injective linear map $j \colon C^r(G;\mathcal B)\to \Gamma{0}(G;\mathcal B)$generalizingthewellknowmap$j \colon C^{r}(G)\to C{0}(G)$ in the case of an 'etale groupoid.
