Remark 90.16.9. We say that a functor $F: \mathcal{C}_\Lambda \to \textit{Sets}$ is a *deformation functor* if the associated cofibered set is a deformation category, i.e. if $F(k)$ is a one element set and $F$ satisfies (RS). If $\mathcal{F}$ is a deformation category, then $\overline{\mathcal{F}}$ is a predeformation functor but not necessarily a deformation functor, as Lemma 90.16.7 shows.
