\(X,F,\Gamma_F\) & The original curve, its function field and its
absolute Galois group.\\
\(p,q,\ell,k\) & The geometric characteristic, size of the constant
field, coefficient prime, and \(k=\overline{\mathbb Q}_\ell\).\\
\(\deg_F,d_v\) & Arithmetic Galois degree and the degree of a closed
point \(v\); geometric Frobenius at \(v\) has degree \(-d_v\).\\
\(G,\widehat G,M,\widehat M\) & The split group, its dual, a Levi
subgroup and the corresponding dual Levi.\\
\(\sigma,\nu_\sigma\) & The prescribed parameter and its character
on excursion data, defined by \eqref{fl:eq:main-full-label}.\\
\(e=(I,f,\boldsymbol\gamma)\), \(S_e\), \(S_e^{\mathrm{fun}}\) & An
excursion datum, its excursion operator on functions with compact
support, and the transposed operator on all functions
(\cite[Definitions~\xnum{I}{fl:def:weil-excursion-datum}
and~\xnum{I}{fl:def:function-excursion-action}]{HuI}).\\
\(T_G,\Xi,\omega_\sigma\) & The connected centre with its reduced
structure, a central lattice, and the central character of
\(\sigma\) (Definition~\ref{fl:def:central-period-lattice}).\\

(Section~\ref{fl:sec:common-descent}).\\
\(x_\alpha(t),E_{a,b}\) & A root group element and an elementary
matrix (Section~\ref{fl:sec:classical-descent}).\\

the terminal space (Section~\ref{fl:sec:char2-d}).\\
\(\varrho,\varrho_i,\Pi_i\) & The standard representation
\(\operatorname{Std}\sigma\) of a classical parameter, an
irreducible summand of it, and the corresponding cuspidal
representation of a general linear group (Section~\ref{fl:sec:classical-descent}).\\
