Lemma 38.43.11. In Situation 38.43.1. Let $b : X' \to X$ and $D'$ be as in Lemma 38.43.6. Let $Q = L\eta _{\mathcal{I}'}Lb^*M$ be as in Lemma 38.43.7. Let $W \subset X$ be the maximal open where $M$ has locally free cohomology modules. Then there exists a closed immersion $i : T \to D'$ of finite presentation such that

$D' \cap b^{-1}(W) \subset T$ scheme theoretically,

$Li^*Q$ has locally free cohomology sheaves, and

for $t \in T$ mapping to $w \in W$ the rank of $H^ i(Li^*Q)_ t$ over $\mathcal{O}_{T, t}$ is equal to the rank of $H^ i(M)_ x$ over $\mathcal{O}_{X, x}$.
