Lemma 85.22.2. Let $\mathcal{C}$ be a site with fibre products and $X \in \mathop{\mathrm{Ob}}\nolimits (\mathcal{C})$. Let $\mathcal{O}_\mathcal {C}$ be a sheaf of rings. Let $U$ be a hypercovering of $X$ in $\mathcal{C}$. For $E \in D(\mathcal{O}_ X)$ the map

\[ E \longrightarrow Ra_*La^*E \]

is an isomorphism.

Proof. This is a special case of Lemma 85.20.2. $\square$
