. The $0$ elements of $X(W)$ which label cuspidal character sheaves are all contained in one family, which we denote by ${{\mathcal{F}}}_0$ and which consists of $0$ elements in total. The elements of ${{\mathcal{F}}}_0$ are given by the $0$ pairs $(u,\sigma)$ where $u\in{{\mathfrak{S}}}_0$ (up to ${{\mathfrak{S}}}_0$-conjugacy) and $\sigma\in{{\operatorname{Irr}}}(C_{{{\mathfrak{S}}}_0}(u))$. The diagonal block of the Fourier matrix corresponding to ${{\mathcal{F}}}_0$ is then described in terms of ${{\mathfrak{S}}}_0$ and the pairs $(u,\sigma)$; see [@C0 §00.0] for further details.
